An agent based Rumor Dissemination for routing in Wireless Sensor Networks

The main problem for Wireless Sensor Networks deployed in environments with no geographical localization system is the uniform distribution of information in the network. For that purpose we propose a new routing protocol based on an Efficient Rumor Dissemination called: Fast Rumor Routing. The FRA protocol optimizes the agent (respectively the query) propagation through the network preventing backward paths. The rumor succeeds to reach far regions in the network in a trajectory as straight as possible, reducing the total overhead of the network. Furthermore, for important and critique data in a real time applications, FRA with replicas (FRA_R) was implemented and tested to ensure a good delivery rate of the query in a short delays and prevent by this way the problem of path deficiency. Simulation results show that the main contributions of FRA protocol are the reduction of: time of path establishment, the overhead caused in the network and consequently the energy consumption.
