ABSTRACT: Heterogeneous Wireless
Sensor Networks (WSNs) have different sensing ranges and computing power in the
midst of various resource constraints such as limited battery power, reduced
transmit power and network potential. This paper proposes new hybrid energy
efficient transmission protocol called Hybrid Transmission Protocol (HTP). The
proposed algorithm focuses on the issues of throughput dreadful conditions and
limited power on mobile nodes due to conflicts in multi-cell wireless networks.
The design principle of the proposed routing algorithm is to introduce a new
border cluster between the sink nodes and the cluster-heads in order to
lengthen the lifetime of the network nodes with minimized energy consumption to
attain energy efficiency. The creation of clusters is done by making use of the
sensor nodes formation that has a Cluster-Head (CH) used for performing the
data aggregation in the sensor nodes of the cluster. Later the data that is
aggregated is transmitted with multiple hops to the base station and in turn,
this process leads to the reduction in the bandwidth through the elimination of
the redundant data present in a cluster. The performance results indicate that
the HTP proposed gained greater network lifetime, better performance and higher
throughput compared to the other available algorithms.
