Effect of mobility on the stability of routes in ODMRP

One of the most challenging issues in Mobile Ad-hoc Network (MANET) is how to establish the most stable, reliable and efficient route in multicast routing strategies to forward the data from one node to other nodes in mobility and crowded environment. In this paper, we study the impact of mobility and scalability on the routing stability performance of On-Demand Multicast Routing Protocol (ODMRP) in MANET. Some metrics will be used to evaluate these effects like number of CBR and control packets that will be generated by the network. Two scenarios will implement with single and multiple sources via NS2 simulator. Results of simulation illustrate that, in term of increase mobility, CBR packet sent will increase by 16.5% and 8.4% in first and second simulation respectively, and receiving CBR packet will be reduced by 2.8% and 5.9% in first and second simulation respectively.
