Most commonly cellular systems use smaller cells to handle high population of mobile users. But this solution leads to higher handoff requests which require good handoff management algorithms which give priority to handoff calls on the expense of blocking the originating calls. Guard channel based schemes are among the schemes that give priority to handoff calls. This work aims to combine the concept of time threshold and load balancing to the existing guard channel based schemes so as to decrease the dropping probability of handoff calls. The Matlab based simulation results show that the proposed systems have good performance in terms of handoff call dropping probability.Keywords

Home security and automation has been a major issue in recent days where crime is increasing and everybody wants to take proper measures to prevent intrusion.In the present research paper, attempts are made to simulate GSM based home security and control system. The result shows that the developed system works efficiently and can work as a platform in developing new systems for weather forecasting, temperature updates and device synchronization.

Smart antennas are usually employed at the base stations to radiate narrow beams to serve different users by using spatial processing. In this paper the use of adaptive antenna arrays on CDMA networks to suppress cochannel interference is carried out using newly proposed SMI-RLS algorithm which will compensate the singularity problem of SMI algorithm and minimizes the complexity of RLS algorithm. The simulation results proved that the proposed SMI-RLS algorithm is able to place deeper nulls than the other algorithms and it has minimum complexity compared to RLS algorithm.Keywords
