Linear Program (LP)-based algorithm called MTS, for lower time complexity generic ad hoc protocols do not work well in hybrid cellular and WiFi ad hoc networks, and may lead to:1) degraded overall throughput, 2) unfair resource allocation, and 3) low resilience to mobility. They propose two approaches to improve the efficiency of ad hoc protocols.First, the base station can run optimization algorithms for the WiFi ad hoc network, for example, to build optimized routes.

so as to avoid network congestion around the base station.Second, mobile devices connected to other access networks can offload traffic from the cellular network to those access networks. DISADVANTAGES;1.Lower time complexity generic ad hoc protocols do not work.2. Existing algorithms achieve at least 10 dB quality improvements and result in up to 80% packet delivery delay reduction. PROPOSED SYSTEM:

We propose a hybrid network, in which each multicast group is either in the cellular in the ad hoc mode.We are propose the THS algorithm. We propose a unified optimization problem that jointly finds the optimal gateway mobile devices, ad hoc routes, and video adaptation, we employ Variable-Bit-Rate (VBR) streams.They propose two approaches to improve the efficiency of ad hoc protocols.1.To build optimization routes.2.To avoid network cogestion around the base station. ADVANTAGES:

1. The links into mobile devices on breadth-first trees of transmission units with higher quality improvement values are given higher priorities.2. The links with higher ad hoc link capacities are given higher priorities.3. The links from mobile devices with higher cellular link capacities are given higher priorities.SYSTEM ARCHITECTURE

IMPLEMENTATION MODULESWe are using five modules:1.Server client module2.WiMax relay networks3.Resource allocation4.Video streaming5.Quality optimizationSERVER CLIENT MODUIEIn this module client server computing or networking is distributed application architecture that partetions tasks or workloads between service providers.A server machine is a high performance host that is running one or more server programs which share its resources with clients.HARDWARE & SOFTWARE REQUIREMENTSHARDWARE REQUIREMENT;Processor - Pentium IVSpeed - 1.1 GHzRAM - 256 MB (min)Hard Disk - 20 GB
