The Impact

Routing protocols can be tested in realistic conditions of Mobile Ad-hoc network (MANET)). The performance of MANET depends on different parameters such as used number of nodes, mobility speed, routing protocols, mobility model and energy models etc. In this paper, researchers made an effort to analyze the impact of energy and mobility on the performance of AODV and DSR routing protocols with varying mobility speed under random waypoint mobility model and radio energy models in the MANET. Detailed simulations have been carried out using QualNet simulator for 50 nodes. Performance of AODV and DSR routing protocols has been analyzed under the premise of performance metrics namely average throughput, average end to end delay and average jitter using CBR traffic patterns.

The Impact

Advances in wireless technology and mobile computing have provided a major impetus towards development of P2P network over MANET. Both peer-to-peer overlays and mobile ad-hoc network share the key characteristics of self-organizing and decentralization; both need to solve same fundamental problem, that is, how to route queries or packets efficiently. Congestion affecting the performance of P2P overlay on wireless ad-hoc network occurs not only due to buffer overflow but also due to error prone nature of the wireless medium used and the mobility of users. When paths of multiple downloading sessions intersect with each other, they mutually cause congestion for each other that result in packet drops. We identified that P2P MANET suffers query performance primarily due to significant congestion during download session. The unawareness of congestion in P2P MANET system may lead to the longer user response time, high overhead and many packet losses. In order to alleviate the congestion problem, we propose a modification to RAON, CANON, which includes congestion awareness for improving the RAON performance. We evaluated our system through simulation, which shows that CAON improves the performance of query success rate, query delay, packet losses significantly. We also evaluated the impact of mobility model on our system by simulating under both Random way point mobility model and Manhattan mobility model.

A mobile ad hoc network (MANET) is a group of mobile wireless nodes without pre established infrastructure or central management with frequent changing topology. In the last few years, various routing protocols are targeted specially at MANET have been proposed however little data is available about the effect of various parameters on the performance of these protocols. In this paper, we assess the impact of several terrain areas and pause times on the performance of the two prominent reactive routing protocols; i.e. AODV and DSR and present the results of our simulations. It is observed that the hop-by-hop AODV perform much better for medium size terrain areas while DSR is suitable for small terrain areas. For larger terrain areas, the average end-to-end delay encountered by AODV is very low compared to DSR.
