Wireless sensor networks drawn huge attention in the recent years due to their vast
implementation scenarios and possible applications in many fields in our daily lives, opening the
venue for a new era of technological evolution in human history.
Still WSN suffer from many constrains affecting their performance and operation, such as the
energy consumption due to the fact that they are battery powered, latency, coverage and
connectivity of the network, which may limits the network life time and operational efficiency.
Careful placement of WSN nodes has been proved to solve some of these issues, a new area in
this topic, is actor nodes placement problem, our work falls into this category.
This work focuses on decreasing the average energy consumption of the WSN nodes, and the
average communication delay in the WSN network by clustering the network and optimizing the
actor's location within each cluster to achieve a better and more efficient network topology.
The Delay and Energy saving by Actuator positioning algorithM (DEMA) outperforms the
average delay and average energy consumption when benchmarked with random, uniform, and
COLA algorithms with around 25% reduction in the average communication delay, and around
40% in the average energy consumption. It also has a topology maintenance phase to readjust the
network to optimal time periodically or when a percent of the node fail. Also it's built on the fact
that the nodes use necessary amount of energy to communicate and not full energy mode as in
other algorithm
