  Energy utilization is a key attribute for energy constrained wireless sensor
networks (WSN) that directly impacts the life time of the network. LEACH (and
its variants) are considered to be the most common energy efficient routing
protocols for WSN. In this paper, we propose an optimized modification of LEACH
that makes use of multi-hop communication, dynamic cluster boundaries and
energy conservation in routing to maximize lifetime of a network. We propose a
multi-level approach to maximize our gains with regards to energy conservation
i.e., i) Dynamic programming based intra-cluster optimization technique has
been proposed ii) Ant Colony Optimization is used for energy efficient cluster
head connection with sink node and iii) Voronoi Tessellation are employed for
efficient coverage planning i.e., dynamic formation of cluster boundaries. In
order to accommodate a more flexible adhoc network, hybrid (reactive and
proactive) event monitoring based on Deep Belief Network has been integrated in
distributed nodes to improve the latency of the system. The results show that
the proposed scheme significantly outperforms the current state of the art with
regards to network lifetime and throughput.
