Research description:

We do research in Wireless Sensor Networks (WSN) and in distributed routing protocol for mobile WSN Mesh topology in the Multi-Sink system.

On the Network Layer:
These techniques will be used to find the best routing algorithm:

• Simulated annealing
• Tabu search
• Particle swarm
• Ant colony
• Harmony search
• Fuzzy logic (triangular)

We will design a new network packet which will be sent between the nodes transferring more data such as hop count, mobility direction, RSSI, SNR, buffer size, and energy in order to choose the best neighbour node.

On the MAC Layer:
We will try to find the best and more dynamic Back-off-time in the Unslotted CSMA. Tabu search will be used as another algorithm. Among the four systems below the most appropriate one will be chosen, regarding energy consumption, and packet delay.

• Single-radio single channel
• Single-radio multi channel
• Multi-radio multi channel 

The Mobility Model is based on:

• Random ad-hoc mobility
• Random directional mobility.
