Performance evaluation of Location-Aided Routing protocols in ad hoc networks

摘要

several geographic routing protocols using location information have already been proposed for ad hoc networks to improve performance of ad hoc routing protocols, such as Location-Aided Routing (LAR) protocols. Through using location information, LAR protocols restrict the search for a new route to a smaller Request Zone of the ad hoc network. This results in a significant reduction in the number of routing packets. This paper presents the performance evaluation of LAR protocol and its derivatives: LAR Box, LAR Step, P-LAR Box and P-LAR Step. The performance evaluation is based on several network metrics such as Packet Delivery Ratio (PDR), Traffic Overhead (TOH) and End to End Delay (EED).
