Abstract
Wireless Sensor Network will enable the reliable monitoring of a variety of
environments. This thesis deal with proposed communication protocol, which can
have significant improvement on energy of (Lifetime) of heterogeneous networks and
increment in data packets transmission from the sensor members to the cluster heads.
Currently DEEC, DDEEC, EDEEC protocols are used for data transmission in
heterogeneous network where data transmitted to the sink, as a result the
communication from the sensor nodes to the cluster heads is not efficient; which is
improved by the proposed protocol . The nodes send data to BS and CHs only when
the sensed attribute crosses a pre-defined threshold, and keep their transmitters off
otherwise. Hard Threshold; in which each sensor nodes compare its sensed attribute
when the sensor nodes cross the value, transmitter reports to CH. In the case of the
Soft Threshold, it is used when sensor crosses hard threshold. Higher value of Soft
Threshold lead to lower power consumption and higher network lifetime. 3-Tier
communication architecture is introduced to minimize the communication distance.
Purposed Protocol approach is 1.5, 1.38 and 1.08 times better than DEEC, DDEEC
and EDEEC respectively, in terms of network lifetime. Which shows that the
proposed protocol is much better than other routing protocols for Wireless sensor
network.
