Enhancing the Performance of Wireless Ad hoc Network with AOLB Geographic Routing Technique

Abstract- A wireless ad hoc network is a decentralized type of wireless network. The network is ad hoc because it does not rely on a pre existing infrastructure, such as routers in wired networks or access points in managed (infrastructure) wireless networks. Instead, each node participates in routing by forwarding data for other nodes, so the determination of which nodes forward data is made dynamically on the basis of network connectivity. To support multimedia applications, it is desirable that an ad hoc network has a provision of Quality of Service (QoS). However, the provision of QoS Routing in a mobile ad hoc network is a challenging task. However, in the last decade, much research attention has focused on providing QoS Routing assurances in MANET protocols. This paper presents a review of the current research related to the provision of QoS in an ad hoc environment and provides the techniques to improve some of the QoS Routing metric using Geographic Routing.
