Abstract
Time division multiple access (TDMA) and frequency division multiple access (FDMA) are two popular multiple access technique that used in several wireless sensor networks. Both TDMA and FDMA have their own advantages and disadvantages. In this article, we have tried to use these two together for reducing the interference of inter-cluster and intra-cluster communication. We have considered a model of sensor network where, there are some high power nodes, which are placed in a regular hexagonal pattern and some ordinary sensor nodes which are placed randomly. High power nodes will act as clusterhead. Inside the cluster sensor nodes communicate with the clusterhead. TDMA and FDMA are being used for both time slot assignment and interference reduction. The proposed system is simulated to show the throughput of the system for different numbers of nodes. It is also shown how the packet loss of the whole system varies with low load and peak load. Our proposed system also compared with the contention based system and shown the improvement over the contention based system.
