Signal reach computation for AODV power threshold in WANET employing Fuzzy Logic

摘要

An Ad-Hoc network is a collection of wireless mobile nodes dynamically forming a temporary network without the use of any existing network infrastructure or centralized administration. Due to the limited transmission range of wireless network interfaces, multiple network "hops" may be needed for one node to exchange data with another across the network [1-4] and to cope up with traffic management routing becomes essential in ad-hoc networks. Table-based routing algorithms used in proactive protocols are computationally intensive and require periodic transmission of status information amongst all network nodes. Also, routing table volume swells with network size and can be large for dense networks. Therefore to cope with possibly rapidly changing topology reactive protocols such as Ad-Hoc On-demand Distance Vector Protocol (AODV) generate routes for unknown destination paths on an as needs be basis. In this paper, implementation of Routing of AODVprotocol using Truetime simulator which is MATLAB/simulink based networked Simulator. Also, this paper presents study of variation in parameters like packet delivery ratio and end to end delay with changes in power. In addition to this, also this paper shows use of fuzzy logic which helps in optimization of signal with the help of transmission power and threshold [10]. In addition to this fuzzy implementation for signal reach, due to change in transmission power and threshold.
