چکیده مقاله:
Ad-hoc networks consist of collections of wireless mobile nodes. Due to mobility, there exists frequent link breakage, packet loss, and need for route discovery. OLSR is proactive routing protocol that is developed for mobile ad-hoc networks. OLSR reduces the network traffic by flooding control packets efficiently and reducing unnecessary and redundant control packets. OLSR reduces the overhead of control packets using a subset of one-hop neighbors called multipoint relays for flooding control packets. Although OLSR is dedicated for mobile ad-hoc networks, but mobility of nodes does not considered in MPR selection procedure. In this paper is assumed that some nodes are stationary and packet delivery rate of the OLSR routing protocol is improved by preventing mobile nodes from being selected as multipoint relay as much as is possible. Simulation results which are implemented on Visualsense simulator, demonstrate that our proposed method reduces the packet loss ratio and number of control packets and consequently increases lifetime of networks.
