Abstract

Network Lifetime of sensor node plays a fundamental role in Wireless Sensor Networks, since they drain out energy during the communication. The hierarchical networks assist in hindering energy loss by exchanging the information at various levels. The Hierarchical levels formed avoid overburdening of single level cluster zones and helps the network to retain energy of cluster level heads. Malicious attack disturbs the regular functionality of a routing algorithm and deviates QoS performance in the network. The existing LEACH-Mobile protocol adopts low energy clustering techniques but, falls short in providing security of the network when there is malicious attack. The proposed Trust Computation for Hierarchical Clustering Network protocol proves itself to be trustworthy by having various trust measuring metrics. It enhances the lifetime by adopting low energy hierarchical protocol and shows improvement of 12% in terms of energy consumption.

基于层次聚类网络的信任计算提高无线传感器网络的生存期
传感器节点的网络寿命在无线传感器网络中起着至关重要的作用,因为它们在通信过程中消耗着能量。分层网络通过在不同层次上交换信息来防止能量损失。形成的层次结构避免了单层次集群区域的过重负担,有助于网络保留集群层次头部的能量。恶意攻击会干扰路由算法的正常功能,使网络中的QoS性能出现偏差。现有的LEACH-Mobile协议采用低能量聚类技术,但在存在恶意攻击时无法提供网络的安全性。本文提出的基于层次聚类网络协议的信任计算方法通过多种信任度量指标证明了其可信任性。采用低能耗分层协议,提高了系统的寿命,能耗降低了12%。
