A comparative study of location aided routing protocols for MANET

Abstract

-Location-aided routing (LAR) is a mechanism which attempts to reduce the control message overhead of Ad-hoc ondemand distance vector (AODV) routing protocol by flooding only the portion of the network that is likely to contain the route to destination. LAR takes advantage of Global Positioning System (GPS) coordinates to identify a possible location of the destination node. Based on this information, LAR defines a portion of the network which will be subject to the limited flooding, thus reducing the total number of the control packet traveling through the network during the route discovery process. GeoAODV is a variation of the AODV protocol which like LAR also employs GPS coordinates to limit the search area used during the route discovery process. However, unlike LAR, GeoAODV does not make the assumption that every node in the network knows the traveling speed and location of the corresponding destination node. Instead, GeoAODV tries to dynamically learn and distribute location information among the nodes in the network. This paper examines and compares through simulation the performance of AODV, LAR, and GeoAODV protocols under different environmental settings.

A Comparitative Survey on Malicious Nodes and Their Attacks in MANET

“…In Nen-Chung Wang et al [8] In this paper author propose an improved location-aided routing (ILAR) scheme to improve the efficiency of location-aided routing (LAR) scheme by using the global positioning system (GPS). They also propose a partial reconstruction process that maintains a routing path.…”

Improving MANET Routing Protocols Through the Use of Geographical Information

“…Geographical AODV (GeoAODV) [4][5][6] is our proposed improvement of LAR zone protocol: it defines the request zone differently than LAR zone, it allows the request zone area to expand after route discovery failures, and it dynamically distributes the node coordinates during route discovery. In this section we introduce the GeoAODV protocol and describe its operation in detail.…”

“…AODV is a stateless reactive routing protocol for MANET, which employs flooding to discover a route to destination. There have been numerous studies that attempted to improve the performance of MANET route discovery through the use of geographical location information [4][5][6][7][8][9][10][11][12][13][14]. This study concentrates on Location-aided routing (LAR) protocol [7][8] and its improvements [5][6].…”
