New MAC Protocol for Fast Data Collection in Wireless Sensor Networks

Wireless sensor network (WSN) is a powerful combination of distributed sensing, computing and communication.These are deployed in number of scenarios, and in most cases, the data collection rate plays the crucial role.The key application scenario of wireless sensor networks is data gathering: sensor nodes transmit data, possibly in a multi-hop fashion, to an information sink.The performance of sensor networks is thus characterized by the rate at which information can be aggregated to the sink.In this paper, after studying the existing approaches, we are looking for an effective protocol, to enhance the rate of data collection in wireless sensor networks.We are introducing a new MAC protocol using asynchronous TDMA.In conventional TDMA protocol, if a device has no data to send during a particular time slot, that slot is wasted.Also, if data is of larger size then it cannot be transmitted in the particular slot.Here, these two problems are addressed and appropriate solutions are encountered by making use of this new protocol.
