Service Discovery for IP-based Wireless Sensor Networks
In a Wireless Sensor Network (WSN), the services that each sensor node can provide must be described according to a standard and possible to discover by other devices.
Protocols such as the well established UPnP (Universal Plug and Play) aim at facilitating the advertisement and discovery of network services and already exist in many computer networks. We suggest to use UPnP for WSNs.
Designing protocols for WSNs, engineers often face battery, memory and computation constraints, which impose proper evaluations to be conducted and when necessary, reasonable trade-offs to be adopted.
The goal of this thesis project is to allow the sensor nodes to announce, discover and use services with UPnP and study the efficiency of the solutions put in place in the context of low-power embedded networks.
Finally, optimizations to the protocol are proposed to render it more lightweight. Among other results, the power consumption of the radio and the latency of Service Discovery are reduced by 20% and over 60% respectively.
