چکیده (انگلیسی):

An Ideal WSNs should operate with the least possible energy required in order to increase the lifetime of the
sensor nodes and at the same time, ensure network connectivity. But the Inherent power limitation makes
power-awareness a critical requirement for WSN, this calls for the need to manage energy in sensor nodes.
Also In order to ensure successful transmission of data from sensor node source to destination, it becomes
necessary to maintain network availability. The network must be resilient to individual node failure which can
happen due to zero power posses by the node and due to security attacks posed on the node and the network.
Dynamic Window Secured Implicit Geographic Forwarding (DWSIGF) routing protocol has proven to be
robust, efficient and resistant to some security attack which causes failure in network availability. However the
extent to which energy is consumed in sensor nodes which deploys DWSIGF as its routing protocol has never
been mentioned. In this research, we performed a comparative study on energy consumption in DWSIGF
routing protocol. Using the first order radio model, we determined the energy consumed in a network. The
protocol (DWSIGF) is matched up against its counterpart SIGF as the traffic is increased. Observation shows
that DWSIGF due to the variable timing assigned to the CTS collection window, CTS signal fails to reach
destination as collection window time expires, thus the need for retransmission. This in turn consumes more
energy than the counterpart SIGF which has a fixed CTS collection time. The simulation work was done using
Matlab 7.0. Energy consumed in the random variant of both protocols (DWSIGF and SIGF) was also observed
to be higher than the priority variant of the protocols.
