quotNovel fuzzy based approaches for efficient Route recovery in mobile ad hoc networks Using nature inspired algorithms quot

Abstract

quotMobile Ad hoc Networks (MANET) have witnessed an intensive research newlineattention in the last decade from the academic and the industrial sectors. It consists of newlinemobile hosts spread across a geographical area, connected to each other via wireless newlinelinks in the absence of any sort of infrastructure. They are self-organizing, selfconfiguring newlineand self-healing wireless networks. newlineRouting is a complex issue in Mobile Ad hoc Networks (MANET) newlinedue to its dynamic and frequently changing network topology. Route failures, newlinepacket collision, bad channel condition and congestion are to be considered newlinewhile designing reliable routing protocol in MANET, since these factors tends newlineto increase the packet loss and degrade the bandwidth and battery power. Reliable newlinerouting protocols for mobile ad hoc networks use many link reliability metrics for newlinefinding these links; four of the most commonly used are Link Expiration Time , newline Link Received Signal Strength , Residual Energy and Available Bandwidth . It is newlineshown that these metrics enhance the reliability and reduce the number of route newlinereconstructions. However, minimization of packet loss, communication overhead are newlinea challenging task to improve the performance. The complexity of networks that newlineoffers multimedia services requires the consideration of multiple routing metrics for newlinerouting decisions. The most important metrics that should be considered for newlinemultimedia services are: delay, bandwidth, jitter, losses etc.quot newline newline
