Abstract

As the demand for mobile ad hoc wireless network (MANET) applications grows, so does their use for many important services where reliability and stability of the communication paths are of great importance. Therefore, a MANET must be able to establish reliable communication channels which are protected by failure recovery protocols. One approach for existing failure recovery protocols is based on using backup paths, or multi-paths. This technique provides for more stable communication channels for wireless services, in particular for MANET applications. But work on such multi-path protocols has focused on stability in the presence of link failure for MANETs. In this paper, we extend such protocols to maintain connection stability in the presence of node failure. Our work is focused on protecting the route of mobile wireless communications in the presence of node failure in order to improve their use in MANETs applications by discovering efficient stable communication channels with longer lifetimes and increased number of packets delivered.

۱٫ Introduction

Wireless networks are formed with interconnecting devices communicating wirelessly within a relatively limited area. Mobile ad hoc networks (MANETs) are a type of wireless network where mobile devices are themselves responsible for communicating with each other without the presence of a centralized infrastructure. Devices in MANETs can typically move in any direction they want and therefore links between them and other devices may frequently change such that the topology of a MANET can be very dynamic [1]. Each device in a MANET is not only responsible for network traffic related to itself but also has to forward unrelated traffic as an intermediary. A crucial problem in multi-hop routing in MANETs is finding an efficient and correct route between a source and a destination, due to the dynamic nature of the network topology in MANETs. One of the important traits of a reliable system is the stability of the connection between a pair of wireless nodes interested in communicating.
