چکیده (انگلیسی):

Fast technical advances and development in wireless communication resulted in the huge consumption of
wireless sensor networks. The nodes in these networks are ready to be sensed, processing the data and
transmitting radio units. While several research works have been conducted related to the power-aware and
energy-efficiency using Cooperative Networking protocol (CONET) that reforms clusters but the multiple
rate remains to be explored. Due to the huge constraint in energy, the resources of sensor networks should
be aimed at increasing the lifetime of sensors. This motivates us to seek a different way for severe energy
constraint to overcome the limitations of the previous works by utilizing periodical data assembly in which
energy efficiency and network scalability is achieved for inter-cluster communication using imbalanced
clustering and multi hop routing. In this approach, ICEE focuses on two main strategies, attain efficiency in
energy and increase scalability of network by making a cluster head choose a relay node accordingly to its
residual energy and distance to base station. To start with first the focus is made on Imbalanced Clustering
Energy Efficient (ICEE) mechanism for periodical data assembly where cluster heads are elected by
localized competition in wireless sensor networks. The ICEE partitions enables the nodes into clusters of
imbalanced size and clusters closer to the base station have lesser sizes than those farther away from the
base station. The cluster heads nearer to the base station keep some energy for the data forwarding during
inter-cluster. The implications of the research reveals that Imbalanced Cluster Energy Efficient mechanism
ensures inter-cluster communication with the help of energy-aware multi hop routing protocol and not only
decide on correct power level but also help to create clusters of imbalanced size. Numerical results
measured in terms of communication energy, power consumption and cluster head probability ratio in
wireless sensor network depict superior performance in comparison with CONET using ns2 simulator.
