“…But there needs special software and hardware's supporting (such as GPS), thus more suitable for some specific networks. In ad hoc networks, the strength of wireless signal has a direct impact on the quality of data transmission, thus using the strength of wireless signal as the measurement indices in the process of route establishment also attracts the attentions of researchers [3]. In addition, the dynamic characteristics and correlation of the wireless link are also used as the measurement indices of route stability in ad hoc networks [4].…”

Abstract. The inherent dynamic and mobile natures of mobile ad hoc networks bring its flexibility and convenience in network deployment and application, but following with serious challenges on the route maintenance synchronously. Selecting the stable routes can reduce the control overloads resulting from the route rebuilding and maintaining process, improve the utilization of limited network resources, extend the network lifetime and provide the QoS guarantee. This paper proposed a method for measuring the route stability based on the information entropy which utilized the degree of uncertainty as the standard for stable route selection. Simulation results showed that the route selected by our method could improve the network performance remarkably.

“…Signal strength information as proposed in [7] is used for the signal stability based adaptive routing (SSA) where, if a node receives a strong signal from a neighbor then the link between them is considered to be stable, otherwise the link is considered as unstable. An enhanced version was proposed in [8] wherein, instead of directly looking into the received signal strength, the difference between the current and the previous signal strength measurements of the link is considered. If the difference is positive the link is considered as a stable link.…”

“…Signal strength values can be obtained from radio device and strength regulator averages strength values [2]. Geunhwi Lim et al also presented an enhanced link stability estimation model for ad hoc networks [10]. In the latter part, we assume free space radio propagation model and used a distance between two nodes, instead.…”

Many routing algorithms, proposed for ad hoc wireless networks, are based on source routing scheme. In routing protocols that use flooding, many routing messages are propagated unnecessarily. Gossiping can be used to significantly reduce the number of routing messages sent. When a route is broken, route recovery and maintenance are executed. However, these procedures consume many resources. With a reactive routing protocol, this leads to increased delay and routing overheads while route repair procedures are carried out. To minimize route breaking, it's important to find a route that endures longer time. Shortest path route has short lifetime especially in highly dense ad hoc wireless networks, and it's due to the edge effect. In this paper, we derive the statistic results of link and path availability properties in ad hoc network, and propose a pseudo gossip routing algorithm based on the link stability. This routing algorithm can select a reliable path that can last longer by using fewer routing messages as to be shown by the simulation results.I.
