1. PhD program in Computing Science and Engineering Cycle 26 Evaluation study of DTN Routing Protocols for WSN data gothering environment Khalil Massri, Alessandro Vernata Supervisor. Prof. Andrea Vitaletti

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

3. A proposed simulation senario for WSN data gathering… See video clip snapshot

4. 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]
