Spectrum congestion refers to the situation where there are not enough frequencies to accommodate multiple radios or radio systems operating simultaneously. For instance, spectrum congestion is not uncommon in the unlicensed band, where multiple WiFi, Bluetooth, and Zigbee radios may compete for spectrum. Although there are many studies on spectrum congestion in the unlicensed band, it is not well studied for a cognitive radio ad hoc network employing dynamic spectrum access. Since spectrum congestion in a cognitive radio ad hoc network incurs severe degradation of overall network performance, a novel spectrum congestion detection method is proposed in this paper to detect and locate congestions in such networks. Specifically, we propose a Spectrum-Aware Split Multipath Routing (SA-SMR) with dynamic channel assignment as a baseline multipath routing protocol, and investigate the feasibility of detecting spectrum congestion based on the statistics of the resulted paths from multipath routing. Furthermore, a cross-layer approach is proposed to deduce the cause of the spectrum congestion by comparing information from multiple layers, so that appropriate mitigation procedures can be carried out. Simulation results show the effectiveness of the proposed scheme, and the effects of the primary users' activities and the cognitive users' strategies.

Cooperative communication represents a way of achieving diversity in wireless network. Cooperative coding is a channel code that exploits user cooperation gains. In this paper we present LDPC codes that have the capability of providing full cooperation diversity, while achieving maximum possible diversity gain and coding gain. We analyze the performance of cooperative communication with LDPC codes over noncooperative or direct communication in Rayleigh fading channel. A traditional three node model is developed to analyze the performance where relay helps to do the cooperative communication. We illustrate that cooperative LDPC codes offers more than 3 dB gain over direct transmission in the high SNR region for MPSK and MQAM modulation even when the inter-user channel is noisy.

Since the introduction of Pervasive Computing, there has been a need for a scheme that partitions computation among local CPU and server for optimal performance without compromising energy consumption. In order to adapt to rapidly changing network and computational resource, partitioning schemes evolved from static to dynamic. A recent approach proposed to move scheduler from server to client resulting in better adaptability hence, improved performance. This work presents UMBASS, an improved mobile device installed scheduler. UMBASS introduces unity (single) metric based scheduling supporting configurable priority for the metric. Design of UMBASS requires minimal computations due to single metric based RPC level scheduling thus making it highly adaptive. The evaluation methodology used in this work is general and can serve as a framework for evaluation of partitioning schemes for smartphone applications. Based on this framework, trace-based simulation results show that UMBASS achieves average speedup gain of 24% over previous best client-server partitioning scheme and 19% over previous best mobile installed dynamic partitioning scheme. Average energy savings are on par with these schemes.

As the complexity of deployments increases, network managers face two problems that we address in this paper. First, the deployment of middleboxes in choke points (between two routers through which all traffic flows), raises concerns regarding robustness, correctness and efficiency. Second, dynamically managing traffic isolation in a network is a very tedious task. In this paper we propose using Software Defined Networks (SDN) and OpenFlow to simplify network management by addressing these two challenges. SDN consists of decoupling the control and data planes of a network. OpenFlow standardizes the way that the controller communicates with the network devices in an SDN architecture. To overcome the challenge faced by deploying middleboxes in choke points, we show how these appliances can be deployed at waypoints. In this architecture, a waypoint is only traversed by traffic that needs further processing. The remaining data flows through the network without being processed by the middlebox. We have developed an application that implements an encryption processing unit that works as a waypoint and we show how OpenFlow can be used to route through the encryption unit only the traffic that requires encryption. To overcome the challenge of dynamic traffic isolation, we show how a network manager can use an application to create, delete and modify virtual local area networks (VLANs) in a dynamic way to achieve traffic isolation. Our implementation provides a GUI to the user so that the administration of the VLANs is greatly simplified.

One of the main aspects of Smart Grid communication network is providing a secure communications network. Smart Grid Network operating center and back office are pretty much secure. The problem starts when smart grid network is extended to connect to homes, commercial building and factories. With this the smart grid network access is opened up to millions of smart grid end user access points. In this paper the different security threats at each OSI layer are discussed. An overview of layer 2 security standards 802.1AE, 802.1X are elucidated. The paper finally concludes by proposing to implement the layer 2 security to achieve complete Smart Grid communication network security.

Tuple Space based Mobile Middleware (TSMM) intends to facilitate coordination of different components (i.e. agents) of supported applications in multiple mobile, unreliable networks, which is a challenging problem. This paper proposes TSMM-specific discovery and communication mechanisms that enable TSMM to provide coordination over multiple networks. The paper also presents an approach of formalizing proposed mechanisms using Mobile UNITY.

Content based services are becoming more popular in recent times. Traditional content distribution networks (CDN) are being employed for efficient content hosting and distribution. To increase scalability and reduce the cost of content distribution, peer-to-peer (P2P) systems are being considered to complement the traditional CDN systems in a hybrid manner. Research works and real life deployments have shown that hybrid CDN-P2P systems are feasible, cheap, and scalable options. However, with increasing concern for energy consumption and hence carbon footprint, energy efficiency of such a hybrid system must be taken into consideration before wider implementation. In our study, we analyze the energy consumption of hybrid CDN-P2P systems and provide indicators to help make decision for service providers. We show that the hybrid systems not only help the CDN providers to reduce server bandwidth, but also reduce a significant amount of energy in the core network. For a moderately popular content, core network will consume 20-40% less energy with a hybrid system compared to a traditional CDN. This will provide incentive for the service providers to adopt hybrid systems and reduce carbon footprint and operational expenses.

Performance of 10G-EPON in streaming IPTV is studied using a synthetic trace generator. Parameters of interest are number of concurrent channels, degree of video compression, average and maximum packet delays, packet delay variance, and buffer sizes in ONUs. It is shown that 10G-EPON can support a large number of concurrent IPTV channels with minimal buffer size at moderate rates of video compression.

Wireless Sensor Network (WSN) is used for the monitoring and control applications where sensor nodes gather data and send it to the sink. Most of the energy of these nodes is consumed in transmission of data packets without aggregation to sink, which may be located at single or multi hop distance. The direct transmission of data packets to the sink from nodes in the network causes increased communication costs in terms of energy, average delay and network life time. In this context the data aggregation techniques minimize the communication cost with efficient bandwidth utilization by decreasing the packet count reached at the sink. Here we propose Two Tier Cluster based Data Aggregation (TTCDA) algorithm for the randomly distributed nodes to minimize computation and communication cost. The TTCDA is energy and bandwidth efficient, since it reduces the transmission of number of packets to the sink. It is based on the additive and divisible aggregation functions at Cluster head. The functions are applied according to data packets generated by each node by considering spatial and temporal correlation. The aggregation function used in TTCDA effectively reduces the packet count reported to the sink and prevent transmission of redundant data packets by improving energy consumption. The performance of algorithm is validated using examples and simulations.

Machine to Machine (M2M) communication has gained much interest in the recent past, both within academia and across different industries. Power saving has become a priority issue recently due to accelerated growth of mobile devices with more and more processor power, more storage capacity, better display technology and much richer-applications. It assumes even greater significance when it comes to M2M devices since unlike hand-held mobile devices which has possibility to get re-charged after certain period of time, many of the M2M devices overall life is almost equal to its one-time charged battery life. This paper proposes an energy-efficient solution for M2M devices to minimize overall energy consumption. Simulation results based on OPNET simulator show that the proposed method significantly improves power saving, especially in time-tolerant M2M applications with long periodic report cycles.
