An improved maintenance strategy in ad hoc on-demand routing protocols for mobile ad hoc networks

In high mobility and high traffic load network situations,the delay time is affected with high end-to-end delay in reactive routing protocols such as aodv. in this paper we proposed an enhanced receiver-based aodv (erb-aodv) routing protocol by improving the maintenance phase in aodv. erb-aodv protocol focuses on decreasing the end-to-end delay and the control overhead in high mobility and traffic load. the receiver node uses a controller agent to update the sender node of the current available path. the agent works depend on the history of receiving data packets. using glomosim,the erb-adov protocol outperforms the aodv protocol in high mobility and traffic load. results show that,in high mobility,the delay is decreased by 81% and the control overhead is decreased by 77%. the delay is decreased by 91% in high traffic load,and decreases the control overhead by -77% compared with aodv protocol. these results show the improvement of network delay using the new maintenance strategy on on-demand routing protocols for manets. © 2016 penerbit utm press. all rights reserved.
