JWCN_V5_N1_RP1 Hanafy M. Ali Journal On Wireless Communication Networks 2320 - 2351 5 1 1 10 Wireless Multimedia Sensor Network (WMSN), Wireless Sensor Network, Castalia and Network Simulator Currently available Wireless Sensor Network (WSN) tools may be adapted for the Wireless Multimedia Sensor Network (WMSN). However, this requires more effort to configure and tune such tools for the requirements of current WMSN. On the other hand, many extensions for available WSN tools were developed to extend their functionalities in order to support WMSN. Although this seems to solve the problem, such extensions are usually developed as layers or plugins over the existing ones, which introduce many performance issues. In this paper, Castalia is extended to support the multimedia content simulation. First, the general multimedia requirements are discussed and defined, then the Castalia is enhanced by adding the defined requirements. April - June 2016 Copyright © 2016 i-manager publications.
