Dynamic Congestion Control with Multihop Scheduling Algorithm For Mobile Ad-Hoc Network

Abstract

Wireless devices are designed to work in co-operative manner in Mobile Ad Hoc Networks (MANETs). These devices are connected via wireless link to communicate with each other. In MANET, transmission failure occurs due to several reasons, such as node mobility, channel collision and abnormal channel conditions. The solution must have capability to handle bad channel condition and connectivity failures in unicast transmission. Joint congestion control scheme with scheduling algorithm is improved for dynamic wireless network by changing scheduling scheme with adaptation model. Our end-to-end delay and throughput bounds are in simple and closed forms, and they explicitly quantify the tradeoff between throughput and delay of every flow. Furthermore, the per-flow end-to-end delay bound increases linearly with the number of hops that the flow passes through, which is order-optimal with respect to the number of hops. This dynamic adaptation mechanism achieves better performance in terms of packet delivery ratio, throughput and end to end delay.
