Optimised reactive resource aware routing for wireless infrastructure-less networks

Abstract

Wireless infrastructure-less networks comprise mobile devices disseminated in radio communication areas without any central coordinator. The nodes communicate directly if they are within the radio range; otherwise, they rely on other nodes. Thus, nodes should act as a router to forward the information to other nodes. The network permits the nodes to be mobile freely and organises arbitrarily; therefore, any node can participate or leave the network independently. Further, nodes in the network consist of constrained heterogeneous resources. Proper utilisation and management of network resources and characteristics are needed to achieve performance efficiency in communication. The paper designs an Optimised Reactive Resource Aware Routing Mechanism to utilise resources effectively and adequately control network characteristics. The proposed mechanism is validated with NS2, and performance is compared with current routing protocols. Results indicate that the proposed mechanism outperforms energy efficiency, packet delivery and resource utilisation.
