Analysis of Traffic Splitting Mechanisms for 2D Mesh Sensor Networks

For many applications of sensor networks, it is essential to ensure that messages are transmitted to their destinations within delay bounds and the buffer size of each sensor node is as small as possible. In this paper, the authors firstly introduce the system model of a mesh sensor network. Based on this system model, the expressions for deriving the delay bound and buffer requirement bound are presented using network calculus theory. In order to balance traffic load and improve resource utilization, three traffic splitting mechanisms are proposed. And the two bounds are derived in these traffic splitting mechanisms.
