This paper introduces Location-Aided Routing (LAR) protocols for mobile ad hoc networks (MANETs), which utilize location information to reduce routing overhead. The authors propose two algorithms, LAR Scheme 1 and LAR Scheme 2, that define a "request zone" based on the expected location of the destination node, thereby limiting the search for a new route to a smaller area. This approach significantly reduces the number of routing messages and improves performance compared to traditional flooding algorithms. The paper also discusses the impact of location error and suggests optimizations such as adapting the request zone with up-to-date location information and local search to further enhance performance. Simulation results show that LAR schemes consistently reduce the number of routing packets per data packet, even at higher speeds and with larger numbers of nodes. The authors conclude by highlighting the potential of LAR in reducing routing overhead in MANETs.This paper introduces Location-Aided Routing (LAR) protocols for mobile ad hoc networks (MANETs), which utilize location information to reduce routing overhead.
