Description

ABSTRACT:

A user would issue a query and expect a response to be returned within the deadline. While the

use of fault tolerance mechanisms through redundancy improves query reliability. We develop a

mathematical model for the lifetime of the sensor system as a function of system parameters

including the “source” and “path” redundancy levels utilized. Data sensing and retrieval in

wireless sensor systems have a widespread application in areas such as security and surveillance

monitoring. Redundancy management of clustered heterogeneous wireless sensor networks

utilizing multipath routing to answer user queries. Which the lifetime of a heterogeneous wireless

sensor network is maximized while satisfying the reliability.
