In order to improve the system capacity of wireless sensor networks and provide efficient approach to resist the wireless communication network channel transient decline

a collaborative forwarding the relay transmission control method for wireless sensor networks was proposed.Coordination between wireless nodes was achieved by joint control and management of network routing and data link relay according to network conditions.Cooperative dedicated bandwidth could be reserved introducing bandwidth allocation factor

and could be regulated dynamically.Focusing on the data acquisition service

all wireless sensor node only needed one or more routes to the coordinator

and the corresponding timeslot in the super frame was allocated by the channel management approach.The effectiveness was illustrated from both theoretical and experimental analysis

and quantitative analysis of competition in the network and the probability of error and the signal-to-noise ratio and the transmit power were presented.Building a collaborative forwarding relay wireless sensor network simulation platform verified the proposed method.
