Mobile sink node properly used in routing protocols can improve network performance. Thus we investigate the state-of-the-art mobile sink based query-based and location-based routing protocols. The latter strategy can be further classified into backbone-based and rendezvous-based routing protocols. In this paper, we first describe the main principles of the most representative routing strategie...

In this paper we present a model for the lifetime of wireless sensor networks. The model takes into consideration several parameters such as the total number of sensors, network size, percentage of sink nodes, location of sensors, the mobility of sensors, and power consumption. A definition of the life time of the network based on three different criteria is introduced; percentage of available ...

In past few years, the domain of data dissemination in wireless sensor networks has been the area of interest to be researched. Whenever there is context of mobile sink groups, the data delivery relates to a complex mechanism because mobile groups have a feature to move in a collective manner. On the basis of previous work, generally the mechanism of flooding is adopted to disseminate the data ...

We completely characterize deterministic strategy-proof and group strategy-proof mechanisms on singlesinked public policy domain. The single-sinked domain can be used to model any allocation problem where a single output must be chosen in an interval with the assumption that agents’ preferences have a single most loathful point (the sink) in the interval, and the preferences are increasing as o...

Abstract Flow caused by a line sink near vertical wall in an otherwise stagnant fluid with free surface is studied. A linear solution for small flow rates obtained and numerical method based on fundamental singularities techniques applied to the full nonlinear problem. The located at arbitrary location away from all boundaries of finite depth. Steady solutions are presented various location. It...

In this paper, we propose the mobility of a sink in improved energy efficient PEGASIS-based protocol (IEEPB) to advance the network lifetime of Wireless Sensor Networks (WSNs). The multi-head chain, multi-chain concept and the sink mobility affects largely in enhancing the network lifetime of wireless sensors. Thus, we recommend Mobile sink improved energy-efficient PEGASIS-based routing protoc...

Recently sink mobility has been exploited in numerous schemes to prolong the lifetime of wireless sensor networks (WSNs). Contrary to traditional WSNs where sensory data from sensor field is ultimately sent to a static sink, mobile sink-based approaches alleviate energy-holes issues thereby facilitating balanced energy consumption among nodes. In mobility scenarios, nodes need to keep track of ...

Due to the battery resource constraints, saving energy is a critical issue in wireless sensor networks, particularly in large sensor networks. One possible solution is to deploy multiple sink nodes simultaneously. Another possible solution is to employ an adaptive clustering hierarchy routing scheme. In this paper, we propose a multiple sink cluster wireless sensor networks scheme which combine...
