摘要：For the position of individual Sensor Nodes (SNs), the node exploitation problem in Wireless Sensor Networks (WSNs) deals with strategies, such that the resultant network satisfies individual constraints. To scatter the sensor nodes randomly across the area to be monitored is a popular method of deploying WSNs. The problem of reasonable rate allocation that maximizes the network throughput in standard topologies of Wireless Sensor Networks (WSNs) is described in this paper. We need to find the optimal rate allocation for the individual end-to-end sessions that maximizes the total proportionally fair throughput of the network in order to monitor the entire coverage area of the WSN while maintaining acceptable network throughput. For the link layer transmission probabilities, we provide closed form expressions for the finest end-to-end session rates for topologies as well as the bounds. For regular WSNs with a slotted Aloha MAC layer we study the aforementioned problem, which provides us with a lower bound for more sensible MAC (Media access control) protocols. By using Telosb nodes our real world experiments validate our theories and results. The different regular topologies as the size of network grows and simulations carried out in Qualnet verify our comparisons.
