Improve network capacity on multi-hop 802.11-based wireless networks

Abstract

This thesis report seeks to study and analyze in-depth regarding various medium access control (MAC) layer algorithms and protocols that have been implemented and proposed for wireless networks and shows a performance comparison of three mobile ad-hoc network with an intention to improve wireless network capacity. Theory begins with a short overview of wireless network and its type like infrastructure base network, wireless personal area network (WPAN), wireless sensor network (WSN) and wireless cellular networks, infrastructure less network. Then short overview of basic MAC algorithms used in wireless medium access control layer. Then special MAC algorithms for world of wireless are discussed. A detailed description of mobile ad-hoc network and its protocols. Finally, it shows performance comparison of three routing protocols of MANET. Using network simulator ns-2 it shows the simulation result.
