Description: Wireless Sensor Networks are a new class of Ad Hoc networks that will find increasing deployment in coming years, as they enable reliable monitoring and analysis of the unknown and untested environment. Ease of deployment, extended range, fault-tolerance and mobility are some of the advantages of using wireless sensor nodes. These wireless sensors are expected to be extremely small and battery operated. Protocols for these networks must be designed in such a way that the limited power in the sensor nodes is used in the most efficient manner.
Currently available wired sensors are made large (and expensive) to cover as much area as possible. Each of these has a constant power supply and communicate their data to the end-user using a wired network. The organization of such a network has to be pre-planned to find strategic positions to place these nodes and then has to be installed appropriately. The failure of a single node might bring down the whole network or leave that region completely uncovered. Current invention proposes protocols to efficiently use the limited energy of sensors thus making it feasible to use wireless sensor nodes.
Advantages
These protocols offer versatility to the users while consuming sensor energy very efficiently in an application specific manner, thus increasing the life of the network by at least 3 times.
Our information retrieval protocol is also shown to be quite generic as it allows users to request any type of information in the form of historical, one-time and persistent queries.
The invention also provides the user with the flexibility to query any node in the sensor network directly.
