Evaluation of routing strategies for wireless sensor networks using realistic simulation conditions

Routing for wireless sensor networks based on gradient is a simple and reliable solution resulting in low information costs for the network package, as well as for the node itself. It is used for convergent traffic, where sensor nodes send messages to the sink node. This work proposes strategies for routing using a confirmation mechanism for different neighbors, where four protocol variations are evaluated in order to monitor and control electrical variables. For simulating transmission failures inherent to wireless sensor networks, it were applied to experiments realistic propagation and error models. Results demonstrate that the protocol based on the Longest distance has a satisfactory package delivery rate in severe conditions specified to the application and acceptable end-to-end delay according RFC 5548.
