Abstract

Position-based routing protocols have become more popular in Mobile Ad hoc network (MANET) due to their advantages in using geographical position information of the nodes to route the data packet to the destination node. Each node periodically sends their geographical position information to its neighbors using beacon packets. Data packet routing in position-based routing protocol uses neighbors' position information, which is stored in the node's neighbors list and the destination node's position information stored in the routing data packet header field to route the data packet from source to destination. Most of the current work in position-based routing protocols assumes that position information in the node's neighbors list for its neighbors is accurate, while in reality, only a rough estimate of this position information is available for the nodes. This paper provides analysis study to realize the effect of position information inaccuracy caused by different mobility parameters on Greedy Perimeter Stateless Routing (GPSR) position-based routing protocol. In general, inaccuracy occurs when inexact position information is used. However, the results from the analysis work shown that the node beacon packet interval-time and node speed mobility parameters have a high impact on position information inaccuracy and have an intense effect in degrading the performance of GPSR protocol in terms of average end-to-end delay, non-optimal route, false local maximum, and routing loop.
