The Routing applications are popular in Wireless Sensor Networks (WSNs). For a practical monitoring environment, the monitoring events may be varied, and so do the data sinks. Most of known applications deal with the monitoring without varied data. The varied event and different sinks are regarded as different monitoring systems. We propose a distributed mechanism to arrange the routing for transmitting...
WSN(Wireless sensor network) depicted as an emerging technology, with its potential applications in the field of territory monitoring and industrial applications. The sensors employed in the surrounding environment will monitor the physical attribute changes such as temperature, humidity, etc. and makes notice of the data being gathered and delivers the gathered information to the (BS) base station...
We consider wireless sensor networks (WSN) powered by energy harvested from the environment, which is assumed to be sporadic and random in nature. Wireless nodes in such networks experience random active and sleep periods depending on their energy availability, leading to intermittent connectivity in the network. This paper addresses the problem of minimizing the multi-hop transmission delay in such...
Wireless sensor Networks (WSNs), is one of the most rapidly growing scientific domain. This is because of the development of advanced sensor nodes with extremely low cost One of the characteristic feature of WSNs compared to the traditional wireless communication networks to reduce “delay” in such networks we introduce replication or “spraying” methods that can reduce the overhead of flooding-based...
The paper describes the concept of neighborhood cooperation in context of the Wireless Sensor Network, in which each node can identify and communicate with neighbors around it. The innovative spatial routing scheme shapes an area where the packet retransmission toward the base station can take effect. In this work, the retransmission rules that use notion of actions limited to node's neighborhood...
A principal factor in sensor network design is energy efficiency. In this work, we propose to extend the lifetime of sensor networks using appropriate choice of sensor node distribution. The key idea of our scheme is to deploy more nodes in areas of extensive energy usage. Using this scheme of sensor node distribution, we use probabilistic angular routing to route data packets from the sensor nodes...
This paper explores the attributes, layering models and objective functions in cross layer designs for mobile ad hoc wireless networks by taking all the statistical characteristics and constraints from the physical (PHY) layer, media access control (MAC) layer and network (NET) layer into consideration. This paper reviews the entire network optimization across all the PHY/MAC/NET layers. At the PHY...
