Energy Efficient and Load Balanced Routing for Wireless Multihop Network Applications

Abstract

Wireless Sensor Networks (WSNs) can benefit from ad hoc networking technology characterized by multihop wireless connectivity and infrastructure less framework. These features make them suitable for next-generation networks to support several applications such M2M applications for smart cities and public safety scenarios. Pivotal design requirements for these scenarios are energy efficiency, since many of these devices will be battery powered placing a fundamental limit on network, and specifically node lifetime. Moreover, the way in which traffic is managed also influences network lifetime, since there is a high probability for some nodes to become overloaded by packet forwarding operations in order to support neighbour data exchange. These issues imply the need for energy efficient and load balanced routing approaches that can manage the network load and not only provide reduced energy consumption on the network but also prolong the network lifetime providing robust and continuous. This work proposes a new energy efficient and traffic balancing routing approach that can provide a weighted and flexible trade-off between energy consumption and load dispersion. Simulation results show that the proposed protocol achieves high energy efficiency, decreases the percentage of failed nodes due to lack of battery power, and extends the lifespan of the network.

Sink mobility aware energy-efficient network integrated super heterogeneous protocol for WSNs

“…These nodes are able to sense different parameters and can communicate with each other as well as communicate with the sink (also called base station (BS)). These nodes operate on small batteries and have limited processing and limited wireless communication capabilities [1,2]. Nodes are independent when deployed in the field because they are able to self-configure and survive.…”

Modeling induction and routing to monitor hospitalized patients in multi-hop mobility-aware body area sensor networks

“…The sensors are equipped with limited energy resources. A major portion of their energy is used to gather data about body organs and transmit it to the end station [3][4][5][6]. During this process, some energy is also dissipated in the form of heat.…”

Modeling Enhancements in Routing Protocols under Mobility and Scalability Constraints in VANETs

“…Every vehicle is equipped with a VANET device (a node in VANET) [3]. In order to exchange information, these nodes can search out and pass on messages via wireless network [4, 5].…”
