Reducing energy consumption and prolonging lifetime of network to reduce the amount of packet loss are important issues in wireless sensor networks. Many researches derive the minimum hop path for each sensor to transmit its corresponding data to the sink. The sensors in the path forward the data. However, some common sensors in many forwarding paths will consume much more energy, and then they will...
In wireless sensor networks, it is an important task to periodically collect data from an area of interest for time-sensitive applications. The sensed data must be gathered and transmitted to a base station for further processing to meet the end-user queries. Since the network consists of low-cost nodes with limited battery power, it is a challenging task to design an efficient routing scheme that...
In order to prolong the network lifetime, energy-aware protocols should be designed to adapt the characteristic of wireless sensor networks. Clustering is a kind of key routing technique used to reduce energy consumption. In this paper, a new clustering algorithm MNLC (Maximum Network Lifetime Clustering Algorithm) for energy heterogeneous sensor networks is proposed. The algorithm uses distributed,...
Energy balance is an important design consideration in wireless sensor networks (WSNs). In this paper, based on GPSR (greedy perimeter stateless routing), a novel location-based routing algorithm for energy balance in wireless sensor networks is proposed to improve the energy efficiency of the routing approach with respect to both of energy level and location information. Simulations show that the...
Intermittent connected mobile sensor networks (ICMSN) have emerged in recent studies, e.g. underwater sensor networks, wildlife tracking and human-oriented flu virus monitoring. In these networks, there are no end to end connections from sensor nodes to sink nodes due to low node density and node mobility. Therefore, conventional routing protocols in WSN are not practical for ICMSN since packets will...
Give a new arithmetic of variable round mechanism to reduce the cluster-heads' death in a round. We analyze the classical hierarchical clustering protocol LEACH, and discuss the existed routing protocols based on LEACH and present their problems. Finally we introduce a new a variable round mechanism. A simulation comparison is made between the traditional constant round and the variable round mechanism...
