With the advancement in Networking and Telecommunication technologies and the increase in mobility necessities, Wireless Networks and its related technologies are becoming more popular nowadays. Since, Wireless and Mobile Networks are still evolving, the technology requires much more optimizations. The traditional Base Station (BS) based Wireless networks and Ad-hoc Wireless networks, apart from having their unique advantages, have some disadvantages too. So, we are working towards a new type of Wireless Networks called Hybrid wireless networks incorporating the advantageous features of both BS based and Ad-hoc wireless networks enabling the wireless end terminals to work in different modes based on the necessities and availabilities. The existing literature in Hybrid Wireless Networks does not include much work in overcoming the performance deterioration due to Interference and also the Power drain incurred because of retransmissions. We propose a novel method for Interference Avoidance and Power Management in the presented work.
