SP-AODV: A Semi-proactive AODV Routing Protocol for Wireless Networks

Abstract

Dynamic and efficient routing is one of the key challenges in wireless ad hoc networks. In this paper, based on a reactive AODV protocol, a novel semiproactive routing protocol, named SP-AODV, is presented that uses proactive routing for some special nodes. The efficiency of the new protocol lies in the fact that some nodes with certain conditions will dynamically update some sections of their routing table like proactive protocol and other nodes operate like reactive routing protocol. Through network simulation, we show that our routing protocol is more efficient than AODV1 .

A Novel Approach for Reliable Route Discovery in Mobile Ad-Hoc Network

“…The performance of the proposed algorithm is compared with traditional AODV [7] and recently proposed SP-AODV [10] in terms of control packet overhead, network packet delivery ratio and Average End-to-End Delay. The proposed algorithm RFBRP outperforms AODV and SP-AODV protocol in term of overhead, packet delivery and end-to-end delay.…”

“…When a node receives a RouteReply packet, information about the previous node from which the packet was received is also stored in order to forward the data packet to this next node as the next hop toward the destination. SP-AODV [10], is also a routing protocol based on AODV [7], which focuses on enhancing the performance of AODV. In this protocol authors presented a semi-proactive approach to find a route.…”

Optimizing Routing in MANETs with Energy Conservation

“…The authors(Dargahi et al, 2008) [11] modified AODV and introduced SP-AODV, where they added a flag value to the RREQ packet. They also included two constants, MinTH and MaxTH, which control the value of a new field called the counter in the routing table.…”
