OLCMCR: ORDERED LOAD-BALANCING COOPERATIVE MULTI CHANNEL ROUTING TOPOLOGY FOR VOICE TRANSMISSION OVER IP BASED 802.11 WLAN

In this paper, we propose a cooperative multi channel VoIP routing protocol for 802.11 WLAN networks that handles the congestion to improve the Quality of routing service. Part of the proposed protocol introduced a MAC layer level solution called Cooperative Multi Channel Routing (CMCR) that effectively handles the multi channel transmission at one hop relay node level cooperative multi channel group. The proposed model controls the congestion in hierarchical order to minimize the resource utilization. Limited bandwidth and a high degree of mobility require that routing protocols for ad hoc networks be adaptive, trouble-free, and energy saving. Here we proposed a new Ordered Load-balancing Cooperative Multi Channel Routing Topology (OLCMCR) for 802.11 WLANs, which handles congestion state. OLCMCR capable to adopt a any WLAN structure with enhanced similar resilience against mobility. And OLCMCR utilizes CMCR to reduce the overhead of route failure recovery, improve route efficiency and reduce data transmissions. Our simulation results show that OLCMCR handles congestion with reduced control overhead in various environments. Also can observe improved packet delivery ratio.
