“…This way, E-HORM increases network lifetime and stability period. The authors in [26] proposed Carrier Sense Multiple Access with Shortest First (CSMA/SF) for addressing energy hole problems. CSMA/SF is a priority based medium access control instead of contention based one as the name may suggest.…”

A single tree topology is a commonly employed topology for wireless sensor networks (WSN) to connect sensors to one or more remote gateways. However, its many-to-one traffic routing pattern imposes heavy burden on downstream nodes, as the same routes are repeatedly used for packet transfer, from one or more upstream branches. The challenge is how to choose the most optimal routing paths that minimizes energy consumption across the entire network. This paper proposes a proactive energy awareness-based many-to-one traffic routing scheme to alleviate the above said problem referred to as Energy Balance-Based Energy Hole Alleviation in tree topology (EBEHA-T). This protocol combines updated status of variations in energy consumption pattern around sink-hole zones and distribution of joint nodes among the trees. With this approach, EBEHA-T proactively prevents sink-hole formation instead of just a reactive response after they have occurred. Performance evaluation of EBEHA-T against benchmark method RaSMaLai shows increased energy saving across the entire network and a marked improvement in energy consumption balance in energy-hole zones. This precludes energy hole formation and the consequent network partitioning, leading to improved network lifetime beyond that of the RasMaLai. OMNET++ network simulation software has been used for the evaluation.

“…Nowadays it has been seen that it is common practise to make a concern on energy efficiency issue by targeting a particular layer of the WSN network architecture. For example, in [5], [16], the authors design routing protocol while targeting energy efficiency parameter. From the literature state of the art of WSNs protocol design it seems that the under layered architecture protocol design is on the way to state of maturity due to lots of concentration on it.…”

Compare the WSN with other conventional network system, the changing or charging the existing battery of sensor node within WSN is a tough job. Therefore, since last decade the effort has been made to design and introduce a large number of communication protocol for WSN with given concern on the performance parameter of energy efficiency and still the key requirements within WSN domain, that how to incrementally expands the energy minimization consuming techniques of sensor battery. The other parameters include latency, fairness, throughput and delivery ratio. In this work, we propose a novel joint cooperative routing, medium access control (MAC) and physical layer protocol with traffic differentiation based QoS-aware for wireless sensor network (WSNs). This is referred to as a Joint Routing, MAC and Physical layer protocol (J-RMP). By blending the classical layered approach and combining routing, MAC and physical layer functions, the proposed J-RMP protocol achieves a solution for energy efficiency in WSNs. Convention ally, the problem of energy efficient protocol design is considered independently at respective layer of protocol stack. This paper has taken a holistic approach of finding solution by addressing the possible energy gain in Routing, MAC and Physical layer together. Firstly, it is seen that communication path with the large number of short hop substantially minimizes energy consumption. This phenomenon is used while instantaneous network information is collected with minimum overhead through the control packets for selecting next hop. Based on the updated network knowledge the next hop neighbor is chosen with reduced control overhead. Further, we describe how J-RMP protocol uses the approach for finding the constrained shortest path for forwarding packets [1], which results in load balancing in WSNs and provide mathematical analysis of node forwarding path determination within network. Finally, we compare our proposed method with existing protocols by ns-2 simulator and confirm that J-RMP outperform in some cases in term of sensitive traffics. The experimental results have proved that the traffic load has been balanced to a certain traffic, and energy efficiency has been achieved by properly adjusting the applied theory. The outcome supports the theory, and proves the effectiveness of our proposed scheme. This kind of protocol should have significant implications for various WSNs application where energy constraint is the main point of concerns.

“…In [18], the device lifetime increased 12 times by deploying a power optimized cooperative relay. In [19], the total transmit power under the constraint of the receiver Bit Error Rate (BER) was minimized and a relay with the maximal residual energy was selected to balance the node energy and overcome the energy hole [20]. However, the overhead of control packets between two data packets wasn't considered.…”

In this paper, an Energy-Efficient Cross-Layer Double Cooperative Media Access Control (ECDC-MAC) protocol is proposed with respect to battery-limited Wireless Sensor Networks (WSNs). In this MAC, to extend the network lifetime, Cooperative Communication (CC) is applied in data transmission between the source node and the destination node. In contrast to the previous works, the relay node in our approach can transmit its own data during the CC. The overhead of the control packets, Channel State Information (CSI) and the total transmit power minimization are considered to reduce energy consumption. Simulation results show that the network energy is saved and the network lifetime is extended.
