In the last few years, saving of energy in the wireless sensor network (WSNs) world has been, and continue to be now an important challenge in the area of WSNs. In this paper, energy aspect has been investigated, with specific regard to routing, MAC and physical layer. We propose a novel joint routing, medium access control (MAC) and physical layer protocol for wireless sensor network (WSNs) based...
One of the major concern of Wireless Sensor Networks (WSNs) is to minimize the energy consumption of the sensor nodes. In multi-hop clustering, sensor nodes closer to the Base Station (BS) deplete their energy faster as compared to far away nodes. Transmission of own data as well as other nodes data by the nearer nodes is the prime cause for this uneven energy consumption. Hence, the nodes closer...
Innovations in technology that have enabled efficient wireless tiny devices propelled the concept of Internet of Things. It is expected that mobile data traffic will experience 8-fold growth between 2015 and 2020 and the number of mobile connected devices will reach 11.6 billion by 2020. Main factors of this exponential growth and wide acceptance are the integration of several technologies and communications...
Aimed at the inapplicability of LEACH protocol for large-scale sensor network and uneven energy consumption, a Distributed Self-organizing Clustering Routing protocol (DSCR) for large-scale sensor network is proposed.

Multilayer Clustered Designing Algorithm is exploited to present MCDA - Hot Spot algorithm; a technique to increase the network throughput by alleviating the impact of hotspot issue on network lifetime. The network nodes in the hot spot region are in a flat layer form in contrast to rest of the network nodes that are grouped into clusters. This design substantially helps in achieving goal above. This...
These days wireless sensor networks are being used in many different fields. Limited energy and efficient usage of energy are the most important factors that should be considered in these networks. Node clustering increases the efficacy of the energy consumption. Each cluster has a cluster head(CH) that is a member of that cluster and its duty is sending and receiving data in the network. So finding...
Industrial Cyber-physical systems (ICPSs) are expected to provide effective solutions for improving the operation of many existing industrial manufacturing systems. Wireless sensor networks in the industrial field is classified as low-power and lossy network due to energy constrained devices, the dynamic environment and a high packet loss rate. Energy efficiency and delivery reliability need to be...
Underwater Acoustic Sensor Network (UASNs) are deployed in sea for exploration of underwater hidden natural resources. There are certain research issues regarding routing and MAC protocol in the deployment of UASNs.

Wireless Sensor Network has constraint with energy and computation. Network Life is based on the way the energy in the battery is used. Continuously sending data along a specific path for long intervals of time, results in large amount of energy consumption. This could eventually lead to network partitioning, which in turn will create a path loss between the sender and receiver. Though several (sensor)...
Wireless sensor networks (WSN) are widely used various applications such as disaster management, search and rescue operation, wild life monitoring, remote patient monitoring, structural health monitoring etc. It provides bridge between the real physical and virtual worlds. In many scenarios, the coverage area of the WSN will be very large and a multi-hop adhoc network needs to be maintained for the...
