Abstract:

This study aims to model the position information inaccuracy in position-based MANET routing protocol. The modeling aids on understanding the position information inaccuracy and assists the researchers to find suitable techniques and mechanisms to overcome the observed problems and improve the performance of the position-based routing protocols. 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 packets to the destination. Each node periodically sends its geographical position information to its neighbours using beacon packets. Nodes which receive the geographical position information of their neighbours store this information in their neighbours list. The data packet routing in position-based routing protocols uses neighbours’ position information, which is stored in the node’s neighbours list,and the destination’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 the position information in the node’s neighbours list is accurate, while in reality, only a rough estimate of this position information is available for the nodes. Position information inaccuracy has a severe impact on degrading the performance of the position-based routing protocols in terms of average end-to-end delay, non-optimal route, false local maximum, and the routing loop.
