A Greedy Location-Aided Routing Protocol for Mobile Ad Hoc Networks
نویسندگان
چکیده
In this paper, we propose an efficient greedy location-aided routing (GLAR) scheme to improve the efficiency of location-aided routing (LAR) scheme for mobile ad hoc networks (MANETs). In this scheme, we first decide a baseline, which is the line between the source node and the destination node, for route discovery. The request packet is broadcasted in a request zone based on the baseline to determine the next broadcasting node. The neighboring node with the shortest distance to the baseline is chosen as the next broadcasting node. Thus, we can find a better routing path than LAR scheme to reduce the network overhead. Simulation results show that the proposed GLAR scheme outperforms LAR scheme. Key-Words: Expected zone, Global positioning system, Location-aided routing, Mobile ad hoc networks, Request zone.

متن کاملImproving Quality of Service Routing in Mobile Ad Hoc Networks Using OLSR
Mobile ad hoc networks (MANET) are constructed by mobile nodes without access point. Since MANET has certain constraints, including power shortages, an unstable wireless environment and node mobility, more power-efficient and reliable routing protocols are needed. The OLSR protocol is an optimization of the classical link state algorithm. OLSR introduces an interesting concept, the multipoint r...

متن کاملA location-aided power-aware routing protocol in mobile ad hoc networks
In multi-hop wireless ad-hoc networks, designing energyefficient routing protocols is critical since nodes are power-constrained. However, it is also an inherently hard problem due to two important factors: First, the nodes may be mobile, demanding the energy-efficient routing protocol to be fully distributed and adaptive to the current states of nodes; Second, the wireless links may be uni-dir...
