Routing protocol in hybrid wireless network which increases quality of service

Wireless network are of two types, Base station (BS) oriented wireless network and Ad hoc wireless network. Base station oriented is single hop that requires fixed base station having better performance and more reliable, whereas Ad hoc wireless network does not have any centralized administration and mobile host are dependent on each other for communication. But when BS failure causes the problems in the network in base station oriented network and rerouting caused by mobility and disrupted connection causes the problems in ad hoc network. Therefore we use here the Hybrid Wireless Network (HWN), is basically a wireless network consisting of mobile nodes communicate with each other with or without any infrastructure support [2]. In HWN mobile nodes communicate with each other using ad hoc mode when they are in range and use BS to communicate when they are out of range. HWN is more efficient, reliable and flexible with seamless handover. wireless communication gains popularity, significant research has been devoted to supporting real-time transmission with stringent Quality of Service (QoS) requirements for wireless applications. A wireless hybrid network integrates a mobile wireless ad hoc network (MANET) and a wireless infrastructure network has been proven to be a better alternative for the next generation wireless networks.
