Wireless communication and mobile computing are rapidly growing segment of the communication Industry, with the potential to provide low-cost, high-quality, and high-speed information exchange between portable devices. The random selection of free data channels in Dynamic Channel Allocation can balance the data channels’ utilization. CACAO method was the final best Method for channel assignment, but it also has some issues, in that method have a random channel assignment it can reduce the QoS in channel assignment. Based on those issues we can develop the new method for channel assignment named as ATIM (Avoiding Traffic and Interfere Method) channel. In Scheduling we can Find the Delay and the Throughput for each channel by using Locations of the nodes and Channel state information (CSI) then Assign Minimum Delay and Maximum throughput Channels. In the Gather Statistic gathers the information’s about using channels, free channels and Traffic Information’s. In Interfere Calculation calculate the Interfere for each channel. In the Channel Adjustment select the best channel for that node and Switch to that channel. ATIM is a good approximation solution in terms of delay and processing time.
Conclusion
The Interfere algorithm proposed a best possible solution for the packet delay and bandwidth allotment in the network by using this interfere method the quality of service is improved by channel assignment scheme called ATIM, to minimize the delay and give the maximum throughput for the dynamic channel allocation scheme. It also reduces the packet delay due to traffic load. It gives an optimal channel assignment solution in terms of minimum packet relaying delay and can also be used as a tool for performance comparison of different network conditions and networking schemes. ATIM is a good approximation solution in terms delay and processing time. Simulation results also show that ATIM achieves (on average) 95 percent of the delay performance. It achieves high throughput and low delay as compared to the CACAO and is applicable to different cell sizes. Channel assignment is one of the components needed to allocate the channel in any form of traffic in wireless networks. The evaluation result demonstrates the best solution for the dynamic channel allocation for improving the quality of service.
