HP-AODV: An Enhanced AODV Routing Protocol for High Mobility MANETs
نویسندگان
چکیده
MANETs (Mobile Ad Hoc Networks) are wireless networks with characteristics such as self organizing or autonomous, multi-hop and resource constrained. These resource constraints includes limited power, bandwidth etc. which in turn increases the difficulty in MANETs routing. The problem space includes route break, control overhead, limited energy etc. Ad-hoc On Demand Distance Vector (AODV) is the most popular routing protocol for MANETs. In this paper, we propose an enhanced version of AODV known as High performance AODV (HP-AODV) which provides better route maintenance by reducing control overhead. The proposed protocol is providing alternate routes by an extra broadcast in case of route failure. These alternate routes are reducing number of control packet effectively. We have done simulation for different Pause time and different number of sources to get the results.

In mobile ad hoc networks, the absence ofinfrastructure and the consequent absence of authorizationfacilities impede the usual practice of establishing a practicalcriterion to distinguishing nodes as trusted and distrusted.Since all nodes in the MANETs would be used as router inmulti-hop applications, secure routing protocols have vital rulein the security of the network. So evaluating the perf...

Mobile Ad Hoc Networks (MANETs) are receiving a significant interest and are becoming very popular in the world of wireless networks and telecommunication. MANETs consist of mobile nodes which can communicate with each other without any infrastructure or centralized administration. In MANETs, the movement of nodes is unpredictable and complex; thus making the routing of the packets challenging....
متن کاملComparative Study of Fuzzy Logic Mobility Based FLM- AODV Routing Protocol and AODV in MANETs
In mobile ad hoc wireless networks (MANETs), traditional protocol like AODV performs well for low mobility of nodes but not for high node mobility. So, it becomes important to consider mobility factor during the path selection procedure of routing protocol. Here, a fuzzy logic mobility based protocol (FLMAODV) that considers the mobility factor is proposed. Due to the consideration of mobility ...
