Cooperative Communication (CC) is a technique that allows no. of nodes to simultaneously transmit the data with the adjacent nodes antenna. It can save power and extend transmission coverage. Topology control objectives to maintain a topology that improve network performance by minimizing energy consumption. In this paper, we evaluate the performance of OLSR based topology control network under highly dynamic environment. From the simulation results, the QoS performance of proposed criterion under different scenario is good.

The main purpose of this paper is to the make the fundamentals of continued growth of broadband wireless sound. The opportunity for BWA/WiMAX to serve those who want to switch to broadband service is huge in many parts of the world where wire line technologies may not be feasible. In wireless channel air link is the most expensive than other system resources and therefore the controlling system element related to capacity in wireless access networks is the main area of consideration. For this we are tryingto implement the entire algorithm for different system parameter and traffic cases to ease the Mobile WiMAX planning problem. The DL:UL ratio assignment was done in an efficient way to provide both directions with the required capacity i. e. 104 users in 10 MHz bandwidth and 216 users in 20 MHz bandwidth.

Wireless mesh technology is one of the most advanced technologies and can be viewed as the technology of the future. A Wireless Mesh Network (WMN) has been formed by connection of number of wireless access points. It is designed to communicate between nodes using the air interface organized in mesh topology and it is a self-forming, self-configuring and multi-hop network. In this paper, we have analyzed the performance of WMN in terms of average end to end delay, throughput and jitter by implementing the CBR (Constant Bit Rate) traffic between nodes. Results showed that number of packets transmitted has a direct influence on the QoS metrics of the WMN.

Frequency spectrum is the scarce resource and need to be optimally used in Global System for Mobile communication (GSM) network. Every operator has a limited frequency band & operator has to plan the network with this limited band. There are various methods for frequency planning. This paper proposes an innovative approach for Automatic Frequency Planning (AFP) for an existing network. In this method, dummy network same as running network is created and then calculated its interference on the basis of allocated frequencies. After calculating interference, automatic new frequency plan proposes to improve exiting interference in network. The proposed approach replaces the current tedious and inaccurate manual process. With this overall GSM network performance & interference reduces significantly.
