Performance Comparisons of Wireless Mesh IP Video Surveillance Models

This paper investigates the wireless mesh IP video surveillance models and evaluates their performance in terms of throughput, End-to-End delay and jitter. Wireless Mesh Network consists of either a wireless or wired backbone network from which Mesh Gateways (MGs), Access Points (APs), wireless Mesh Routers (MRs) and Mesh Client (MCs) are linked together through carefully designed topologies. WMN networks have the advantage of high reliability, scalability and low capital outlay. The H.264/AVC standard is a joint standard for video compression promoted by the International Telecommunication Union Telecom Sector and the ISO/IEC. The H.264/AVC standard specifies four video formats: Common Intermediate Format (CIF), Quarter CIF (QCIF), Sub Quarter CIF (SQCIF) and 4CIF. Results in this work show that flow throughput is half the network throughput when the hop count for a given topology is two. Additionally, at fixed number of nodes, the Tree Mesh topology outperformed the Fork Mesh and Cross Mesh topology by a factor of 2.8 and 7 in End-to-end and jitter terms respectively.
