Abstract :
With the advance of wireless communication technology, portable computers with radios are being increasingly deployed in common activities. Applications such as conferences, meetings, lectures, crowed control, search and rescue, disaster recovery, and automated battlefields typically do not have central administration. In adhoc networks, each host must act as a router since routes are mostly multi hop. Nodes in such a networks move arbitrarily, thus network topology changes frequently. The protocol termed ODMRP is a mesh-based instead of tree -based, multicast protocol that provides richer connectivity among multicast members. The major strengths of ODMRP are its simplicity. We can further improve its performance. We propose new techniques to enhance the effectiveness and efficiency of ODMRP. Primary goals of enhanced ODMRP: Improve adaptivity to node movement patterns. Transmit control packets only when necessary, Reconstruct routes in anticipation of topology changes, Improve hop-by-hop transmission reliability, and eliminate route acquisition latency.
