The energy consumption is one of the main problems which remain to be addressed in wireless sensor networks (WSNs). Therefore, in recent years several clustering routing protocols for homogeneous and heterogeneous sensor networks have been proposed since these protocols are playing a key role in reducing energy consumption of the WSNs. A new Multi-Level Energy-Efficient Clustering (MLEEC) heterogeneous...
In this paper, we propose an energy-efficient on-demand multicast routing protocol (EMP) for wireless ad hoc and sensor networks. The design objective is to prolong the network lifetime of such networks. For this purpose, EMP introduces the strategy of energy critical avoidance in the process of on-demand construction of multicast routing trees. That is, those energy-critical nodes in the network...
As the use of wireless sensor networks (WSNs) has grown enormously in the past few decades, the need of scalable & energy efficient routing and data aggregation protocol for large-scale deployments has also risen. LEACH is a hierarchical clustering protocol that provides an elegant solution for such protocols. One deficiency that affects the performance of the protocol is existence of very large...
The nodes in a sensor network are severely constrained by energy. Reducing the energy consumption of the nodes to prolong the network lifetime is considered a critical challenge while designing a new routing protocol. In this paper we propose a new power-aware, adaptive, hierarchical and chain based protocol - CCPAR (Clustered Chain based Power Aware Routing) that utilizes the periodic assignments...
This paper presents an energy-aware routing protocol, which uses learning automata concepts for wireless sensor network that is an approach to increase the network lifetime. Moreover, this protocol is scalable and can be used in various places. This approach has the advantage of decreasing energy consumption in order to increase network lifetime and manage routing discovery procedure to find best...
In this paper, a centralized hierarchical-based routing protocol, that distributes energy load among sensor nodes based on their residual energy, is proposed. The performance of the proposed protocol is evaluated via intensive simulation. Simulation results show that the proposed protocol outperforms the well-known Base-Station Controlled Dynamic Clustering Protocol (BCDCP) in terms of network lifetime...
Wireless Video Sensor Networks are foreseen to be of a paramount importance in realizing a wide spectrum of applications, mainly surveillance, target tracking and environment monitoring. In this paper, we propose a combination of an improved clustering algorithm and directed diffusion, a well-known data-centric routing paradigm in sensor networks. On the one hand, clustering allows for saving bandwidth...
Wireless sensor networks (WSNs) consist of small nodes with sensing, computation, and wireless communication capabilities. A number of routing algorithms based on learning automata technique have been proposed for communication networks. However, there has been little work on the effects of cellular learning automata on the performance of these algorithms. One approach to prolong lifetime of sensor...
Sensors are energy constrained, which leads to possible selfishness as the sensor may decline to forward packets for other nodes. Sensors also face the problem of unfair depletion of their energy if communication protocols were energy-unaware. To address the above concern, we propose the dynamic Bayesian game approach: our algorithm derives mutually acceptable path selection strategies between the...
Putting constraints on performance of a system in the temporal domain, some times turns right into wrong and update into outdate. These are the scenarios where apposite value of time inveterate in the reality. But such timing precision not only requires tightly scheduled performance constraints but also requires optimal design and operation of all system components. Any malfunctioning at any relevant...
Because of the lack of a global naming scheme, routing protocols in sensor networks usually use flooding to select paths and deliver data. This process although simple and effective, is very costly in terms of energy consumption, an important design issue in sensor networks routing protocols. Cluster-based routing is one solution to save energy. In this paper, we propose a combination of an improved...
In the last few years, wireless sensor networks have gained a lot of interest in the research field. WSNs consist of small nodes with sensing, computation, and wireless communications capabilities. Many routing protocols have been proposed for WSNs. Most of the hierarchical algorithms proposed for WSNs concentrate mainly on maximizing the lifetime of the network by trying to minimize the energy consumption,...
Wireless Sensor Networks (WSNs) are highly distributed networks of small, light weighted, wireless nodes deployed in large numbers. These sensor nodes are immobile, non rechargeable with limited energy. The cluster-based protocols make judicious use of this limited energy. LEACH-C (Low Energy Adaptive Clustering Hierarchy-Centralized) has a drawback, a lot of energy is consumed by the nodes to send...
