Sensor Network Architecture for Multi-Media Traffic

The desire for more intelligence in the battlefield has given rise to the idea of routing video images over wireless sensor networks. This would apprise the combat decision makers with actual images of battlefield developments and allow them to make sound decisions. To achieve this objective, the characteristics of video traffic must be studied and understood. This paper focuses on evaluating the possibility of routing video images over a wireless sensor network. Video traffic is modeled and simulations are performed via the use of the Sun Small Programmable Object Technology (Sun SPOT) Java development kits configured in three different network topologies: the star topology, binary tree topology and chain topology.
