On-demand Multi-Path Balancing in Wireless Mesh Networks

In recent years, while Mobile Ad hoc Networks still have many challenges to become popular because of dynamic topology and security vulnerabilities, wireless mesh networks (WMNs) with static transit access points (TAPs) are emerging as the best solution for wireless communication. Much of recent work in routing for wireless mesh networks (WMNs) has focused on overhead reduction, performance improvement and security enhancement for ldquomulti-channel, multi-pathrdquo environment using single or multi-radio. However, to the best of our knowledge, there is no current work considering the balancing between the numbers of multi-paths can be used and the needed transmission data in each communication session within the consideration of loss rate. This paper proposes the On-demand multi-path balancing protocol (OMB) with an effective algorithm to balance the number of multi-paths can be used and the needed transmission data in each communication session for wireless mesh networks (WMNs) environment. In wireless communication, this balancing is very critical to reduce routing overhead and improve throughput which directly improve routing reliability. Using a threshold to choose the optimal number of disjoint paths and scheduling the transmission time for single radio nodes, we make our routing protocol perform much better. The simulation results show that OMB improves throughput and reduces overhead, especially in case of big size data transmission.
