Multi-metric routing decisions for ad hoc networks using fuzzy logic

Abstract

wireless networking is one of the current attractive fields for researchers in current era. The ad hoc network is a separable part of wireless networking which facilitate the users to perform communication among mobile terminals with limited bandwidth. But as these networks did not follow any physical topology for installation therefore the risk of security attacks an threats are higher in ad hoc networks. Various attacks such a eavesdropping, spoofing, denial of service are difficult to detect in wireless ad hoc networks. So many researchers have been conducted in this field till now but most of them are not capable to achieve high level security of data plane in ad hoc wireless networks. A novel approach for securing data plane in AHNs has been developed under this study. The PRO-OLSR is a combination of fuzzy based system with OLSR routing protocol. The essential parameters like average delay, packet delivery ratio, direct trust and attack suspected ratio are used as an input membership function to fuzzy system. And on the Basis of the output of FIS the next hop for data delivery is elected. The simulation is done in MATLAB and results are generated to proves the proficiency of PRO-OLSR technique.

A Distributed Routing Approach for Vehicle Routing in Logistic Networks

“…The vehicle sends requests to the different vertices regarding package stocks and the destinations and due times of those packages. For these requests, a concept is borrowed from communication networks: the route discovery in source routed ad-hoc networks [6]. The vehicle sends a request for information about loadable packages, this request propagates from vertex to vertex similar to a route request in communication networks.…”

Analysis of Decision Making Operation In Cognitive Radio Using Fuzzy Logic System

“…Basically, Fuzzy Logic (FL) is a multivalued logic that allows intermediate values to be defined between conventional evaluations like true/false, yes/no, high/low, etc. We note that Fuzzy Logic has been already proposed for use in the context of telecommunication system, e.g., for QoS routing in wired networks [5], route caching decisions in wireless adhoc networks [6], radio resource management [7] and channel selection in cellular networks [8]. An interesting survey on the usage of Fuzzy Logic techniques in the telecommunication field can be found in [9].…”

Fuzzy Controller Based QoS Routing Algorithm with a Multiclass Scheme for MANET

“…Fuzzy logic exploits the pervasive imprecision, uncertainty and partial truth of the real world using simple linguistic statements and thereby achieves tractability, robustness, and low solution cost [11,[13][14][15][16][17][18][19]23]. Fuzzy logic based decision algorithm influences caching decisions of multiple paths uncovered during route discovery and avoids low quality paths [11,[14][15][16][17][18][19].…”

“…Fuzzy logic based decision algorithm influences caching decisions of multiple paths uncovered during route discovery and avoids low quality paths [11,[14][15][16][17][18][19]. Differentiated resource allocation considering message type and network queue status is evaluated using fuzzy logic scheme [11].…”
