A Cross-layer Multiple Sink Mac Protocol with High Power Header Transmission

To design and improve the working of wireless network, a new technique is proposed in cross-layer by merging the concept of multiple sink and high power header transmission. Information is interchanged between two or more layers of protocol stack to evaluate the effect on lifetime is main thought of the cross-layer design and by splitting the information between different layers we get better performance results. In this proposed work, the three layers of the protocol stack are used, which are: physical, MAC and network layer. The proposed work is the combination of multiple sink with high power header transmission in cross layer is used to save power, reduce collision, deceasing time delay is done by using the high power header. The purpose of using high power header (RTS/CTS/ACK) transmission is that the other neighbor nodes go on sleep mode that are in range of sender node and receiver node goes in active mode . By this collision is avoided, retransmission is reduced and power is saved. In this proposed work, the entire area is divided into the grid form and then the nodes are deployed in that area. Multiple sinks are placed, where the density of the nodes is high. Multiple sink is used rather than single sink in ring shape structure. The distance factor is reduced by using multiple sink. The nodes transmit there data to nearest sink. So, less power is used by the sender nodes to transmit data and less power is consumed by the receiver nodes and network lifetime is increased. Due to minimum distance from source to destination the delay factor is also reduced. Keywords—Cross layer, power consumption, sink, high power header, wireless sensor network (WSN).
