To maintain the latency and energy secured data transmission, super frame structure is important with MAC protocol. We propose a new clustering algorithm and PON-based structure to balance the network traffic and limit the network size. We also analyze effect of super frame size on network delay and energy consumption.
We have seen that the requirement of sensor nodes in a U-city is extremely high. To get the appropriate services from the sensor nodes of u-city we have to consider the delay, energy consumption and network size of each Wireless Sensor Network (WSN). Zigbee provides a possible solution to reduce the number of hops by dividing the whole sensor network into several clusters, but the latency is a prime...
