Embodiment Construction

[0032] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0033]According to the characteristics of wireless sensor network, a class of SMAC protocol is proposed to use the periodic listening / sleep mechanism to divide the network nodes into different virtual clusters. It adopts the RTS / CTS / DATA / ACK data exchange mechanism of IEEE802.11 and the multi-hop method and the upper-layer routing protocol to achieve data transmission. For the SMAC protocol, since the nodes between different clusters have different synchronization wake-up times, the data transmission latency of each hop has a large uncertainty; the SMAC protocol also needs to maintain the scheduling table and routing table of the neighbor nodes. The multi-hop delivery must be supported by the upper-layer routing protocol, so the storage capacity of the node is required to be high, and the control overhead is large. In order to solve the above...

Abstract

The invention relates to a cross-layer wireless sensor network MAC protocol communication method and system and belongs to the technical field of wireless sensor networks. A network is divided into zones of different classes according to different skip distances between nodes and SINK nodes. A working manner that periodic scheduling is performed on nodes in all regions is adopted and each period is divided into a periodic data receiving time frame, a periodic data transmitting time frame and a periodic sleep time frame. Periodic scheduling of nodes of adjacent zones is set in a staggered mode and data are transmitted to nodes at the low class until the SINK nodes. The requirement for synchronization of the network nodes is lowered and waiting time delay of data transmission of each skip is reduced. The class of the nodes is used for selecting receiving nodes in the data transmission process and an MAC and a router of data transmission are combined together. Thus, support of an upper-layer routing protocol is not needed, control expenses are reduced and the cross-layer wireless sensor network MAC protocol communication method and system are easy to achieve.

Description

technical field [0001] The invention relates to a MAC protocol communication method and system of a cross-layer wireless sensor network, belonging to the technical field of wireless sensor networks. Background technique [0002] The lifetime of wireless sensor networks is limited by the lifetime of nodes powered by batteries. Therefore, under the premise of considering the application requirements of wireless sensor networks, energy efficiency is the primary consideration in the design of wireless sensor networks, involving all protocol layers. The MAC protocol of the wireless sensor network is at the bottom part of the wireless sensor network protocol. It determines the use method of the wireless channel and directly affects the use efficiency of wireless resources, network throughput and delay and other important performances. It is the key network to ensure efficient communication in wireless sensor networks. one of the agreements. [0003] The limited energy of wireless...
