Deployment of TCP University of Bridgeport (UB) to Control Law Enforcement Department over Wireless Mesh Network

Transmission Control Protocol (TCP) is the most reliable protocol. That was previously introduced for wired networks only. Lately the TCP started to act poorly for several factors due to the advent of wireless network. The represented factors which need to be addressed are recovery mechanism, backup mechanism, mobility, congestion window and maximum packet size. Based on existing variants, new were introduced. The most two debated variants are Vegas and Westwood which motivated many researches. However, the number of studies proved that Vegas could perform more efficiency than other variants during the congested network whereas Westwood could consume less bandwidth. Hence, in our previous publications, we already proved by integrating some features of Vegas and Westwood to get better and more stable variant even in high congested network. It is called TCP University of Bridgeport (TCP-UB).Based on a previous simulation, TCP-UB proved a high efficiency, less bandwidth consumption and stability from static and mobility point of view. Therefore, in this paper we are using NS2 simulator to perform TCP-UB over wireless mesh network supported with manhattan mobility model. It provides robust and faster transmission service among several police stations in Connecticut, USA.Furthermore, we are comparing TCP-UB with Vegas and Westwood from a static and mobility point of view based on bandwidth consumption and congestion window scenario. On the basis of findings, we validate that TCP-UB is also better performer even over wireless mesh network.
