In this paper we present a full performance analysis of an energy conserving routing protocol in mobile ad hoc network, named EM-AODV (Energy Multi-path Ad-hoc On-demand Distance Vector routing). EM-AODV is a reactive routing protocol which combines two mechanisms used in the basic AODV protocol. AODV and most of the on demand ad hoc routing protocols use single route reply along reverse path. Rapid...
Multi-path routing protocols for MANET are deemed superior over conventional single-path routing protocols as the former reduce end-to-end delay, increase reliability and provide robustness. However, the shortest path routes resulting from shortest multi-path routing, such as AOMDV, cause the area congested and thus its effectiveness is decreased. This paper proposes a novel Ad hoc On-demand Multipath...
AODV is an on-demand routing protocol for mobile ad hoc network, with advantages of low load of control, low power consumption as well as low-bandwidth overhead. The routing table in AODV, however, maintains only one route to the specified node. Therefore, the source node needs to re-initiate route discovery process as a route fails. To solve this problem, an improved method is presented in this paper...
A Mobile ad hoc network is a collection of wireless nodes that dynamically organize themselves to form a network without the need for any fixed infrastructure or centralized administration. The network topology dynamically changes frequently in an unpredictable manner since nodes are free to move. Support for multicasting is essential in such environment as it is considered to be an efficient way...
In this paper an upgraded protocol referred to as Rate Adaptive Sustainable Physical Activity in Neighborhoods (RA-SPAN) protocol is proposed. In this protocol the power saving algorithm of SPAN is integrated with dynamic switching of data rates. Power consumption of nodes is reduced by cross-layer signaling between MAC and Network layers as in the SPAN protocol and dynamically electing the coordinators...
In recent years, improved performance of wireless communication technology and lighter mobile terminals that have advanced functions have encouraged consideration of ad-hoc networks, which are temporary networks for the exchange of information among mobile wireless terminals. The features of ad-hoc networks include such advantages as not needing a network infrastructure and multi-hop communication...
