In Wireless technologies are able to provide mobility and portability that makes it more attractive as compared to wired technologies. WIMAX (Worldwide Interoperability for Microwave Access) is a telecommunications protocol that provides fixed and fully mobile internet access. Wired network refers to interoperable implementations of the IEEE 802.3 and WIMAX which refers to interoperable implementations of the IEEE 802.16 wireless-networks standard. A LAN (wired) is a data transmission system designed to provide location dependent network access between computing devices by using a cable infrastructure. The radio range and data rate of WIMAX are much better then Wired network but, on the basis of cost WIMAX is expensive. Now this paper proposed a new hybrid network that is the communication between two different technologies on the basis of Foreign Agent (FA), Home Agent (HA) and Mobile Host (MH). Now the FA is worked as a interface in between wired and WIMAX network and FA is connected with wired network to synchronize the communication with WIMAX, first the request is goes to FA then to network. The combinations of these two technologies are not very expensive and also better than wired. In previous there is no such work done on Wired-WIMAX hybrid network. Their performance will be measure on the basis of performance metrics.

Mobile ad hoc network is a collection of wireless movable node. Movement of nodes results in a change in routes, requiringsome mechanism for determining new routes, Verity of routing protocol exist under MANETs for managing network but all existing routing technique spread maximal overhead so location aware base routing technique is applied that provide minimal overhead as compare to existing routing protocol, In mobile ad-hoc network energy constraint devicesare used the motive is to minimize required power need for data transmission and increase reliability of data delivery.In this paper minimizationof routing overhead is achieved which increasenetwork life time, save energy and increase packet delivery ratio. E-AODV-LAR approach is proposed whichprovide more reliable as well as minimum routing overhead, through results analysisis done on the bases of all network parameterand get efficient technique for MANETs environment.
