Efficient Data Communication and Frequency Reuse in MANET

Mobile ad hoc network (MANET) is a infrastructure-less and also a continuously self-configuring network of the mobile devices without having to be connected to any of the fixed physical link. The wide network loads considered for the MANETs are being increasing as the applications evolve. This focuses on the improvement in the bandwidth efficiency, efficient data communication and frequency reuse throughout the environment. MAC protocol for the wireless networks is classified as coordinated MAC protocol and uncoordinated MAC protocol. For high loaded MANETs on uniform distribution Coordinated channel access protocols has been well suited and for the non-uniform load distribution these protocols are not well suited as the uncoordinated channel access protocols lack in the on-demand dynamic channel allocation mechanisms. In order to address this problem, we present a cooperative load balancing strategy and light weight dynamic channel allocation mechanism that are applicable to cluster based MANETs. These mechanisms improve the performance in terms of efficient data communication, throughput, frequency reuse and inter-packet delay variation. It is crucial for MANET not only to adapt to the dynamic environment but also to efficiently manage the bandwidth utilization.
