Evaluation study of DTN Routing Protocols for WSN data gothering environment

Khalil Massri, Alessandro VernataSupervisor. Prof. Andrea Vitaletti

• A brief overview of our recent work– Evaluating a number of DTN routing protocols

proposed recently in the literature using different mobility models in an environment of WSN for information gathering [1].

– We use the java based Opportunistic Network Environment simulator THE ONE [2]

– We have implemented some RPs and MMs (recently proposed) also modified others already existed in the simulator to adopt our environment.

• A proposed simulation senario for WSN data gathering…

See video clip snapshot

• For now we are using the following RPs – six included routing protocols [2]: Direct Delivery, First Contact,

Spray-and-Wait, PRoPHET, Max-Prop and Epidemic. we modify them to rout the message to any sink node

– Another three RPs are implemented by us• Context aware opportunistic routing (SCAR) [3]

• Fault-Tolerance Based Adaptive Data Delivery routing (FAD) [4]• Routing Based on Fuzzy Decision Mechanism (Fuzzy Spray) [5]

• With the following Mobility Models– Levy Walk [6] (implemented by us)

– Random Waypoint, Random Walk (already implemented in ONE) [2]
