This paper presents an improved clustering routing protocol, ILEACH which based on the characteristic of limited energy of wireless sensor networks to prolong the lifetime of the whole networks. It takes nodes' residual energy into consideration during the process of cluster heads being elected. The constraint threshold of distance is used to optimize cluster scheme. Furthermore, it also constructs...
Cluster-based LEACH routing protocol has the good adaptability for large-scale wireless sensor network, but the existing algorithms may improve the network lifetime through adjusting the threshold, which could make the number of cluster-heads in one certain area more or less, due to ignoring the number of cluster-heads in the process of cluster-heads decision. An optimal cluster-heads algorithm in...
The wireless sensor network is characterized by its density in number of deployed sensors. In reality, sensors in the same region collect and forward, in general, the same information. In order to conserve nodes energy, it is necessary to keep active a set of nodes while others can sleep. In this paper, we present a new topology control protocol (GECP) for wireless sensor network that extends the...
Wireless body area sensor networks will revolutionize health care services by remote, continuous and non-invasive monitoring. Body area sensor networks (BASN) should monitor various physiological parameters of a person for a long period of time. Thus, efficient energy usage in sensor nodes is essential in order to provide a long life time for the network. This paper investigates the effect of adding...
This paper proposed a density-awareness and delay-sensitive (DADS) data collecting scheme for wireless sensor networks. This scheme exploits static sink and mobile sink simultaneously to collect data from the whole network. In this way, DADS can solve the premature network partition problem, resulting from the heavy traffic load in the static sink's vicinity. On the other hand, the coexistence of...
There are two kinds of data collection in wireless sensor network: passive and active. We here propose an adaptive, energy-efficient clustering protocol (AEEC) which is applicable to both passive and active data collection. The proposed protocol selects cluster heads according to the rank of node remaining energy and the number of node neighbors. Unlike traditional clustering protocols, it is an adaptive...
One of the most prominent and comprehensive ways of data collection in sensor networks is to periodically extract raw sensor readings. This way of data collection enables complex analysis of data, which may not be possible with in-network aggregation or query processing. However, this flexibility in data analysis comes at the cost of power consumption. In this paper, we develop ASAP, which is an adaptive...
