5. 4. Implementation and performance analysis of star-based mesh network

   University essay from JTH, Data- och elektroteknik; Tekniska Högskolan

   Author : Muhammad Haq; [2011]
   Keywords : WSN; PAN-coordinator; Full-function device; Reduced-function device; Mesh topology; Beacon Network simulator; NS-2; Shadowing model;

   Abstract : The goal of the thesis is to design the star-based mesh topology by introducing multiple pan-coordinators (hub/switches) under a multipath-fading environment and to improve the data transaction rate of a network which usually gets worst when there is a single pan-coordinator for synchronization of devices in conventional mesh topology; also reduce the hop-count as least as possible. Most of the work has been done on NS-2 network simulator; therefore the research model which has been used here is a simulation model. READ MORE
