Research Issues in Sensors and CloudsBY: NILAMADHAB MISHRA | Category: Technology | Submitted: 2012-11-24 00:20:50
Article Summary: "Here some efficient static and dynamic task management and re tasking issues are discussed along with the VANET to cloud issue..."
Efficient task management in WSN
The task management in wireless sensor network has a potential impact towards fulfilling two broad objectives.
*functional longevity of sensor network.
*performance satisfying application specific -QOS.
He treats each sensor node one task issue entity for which protocols/algorithms are developed to save energy.
Prof. Stefen Olariu mainly decorated the subjects of optical task management through centralize approach and distributed approach; which are further labeled as centralize task management and distributed task management. He undertakes that each task can be itemized as tuple having set of parameters which further requires co-operations from a team of sensors call as task work force for its efficient executions.
The speaker describes the leader selection algorithm in centralize approach in which a task leader is selected among the candidate sensors having maximum energy level such that the leader can capable to coordinate the selection of work force to perform certain task and also able to perform various activities like TDMA frame advertisement, allocations ,bidding ,selections and many more . This algorithm bashes to trail a series of steps like call to work-leader election-work force selection-task execution- result sending to accomplish an optimal, energy efficient and energy aware task management into a specific area of interest in wireless sensor network.
Taking VANET to the Cloud
Prof. Olariu has explained how Vanet have huge potential societal impact, An overnight success with automotive industry, various government agencies (USDOT, FCC, etc), and standardization bodies: ASTM, IEEE, SAE, ISO, Emergence of projects and initiatives, Car-2-Car communication consortium, Vehicle Safety Consortium, Vehicle Infrastructure Integration and Networks on Wheels.
Main characteristics are uses vehicles as network nodes, vehicles move at will relative to each other but within the constraints of the road infrastructure. Communications are basically on Vehicle-to-Vehicle (2V), zero-infrastructure, Vehicle-to-Infrastructure (V2I), roadside devices, WAVE/DSRC/802.11p.
Cloud computing services includes three broad ways of viewing cloud computing based
* Infrastructure as a Service (IaaS) also known as Hardware as a Service (HaaS)
* Software as a Service (SaaS)
* Platform as a Service (PaaS)
As cloud computing is evolving by leaps and bounds the boundaries between the services are nebulous and still evolving.
A cloud in your parking lot can considered as the parking lot of a typical enterprise on a typical
Workday hundreds/thousands cars go unused for hours on end. Why rent computational/storage resources elsewhere. We have them in your own backyard. This is the key concept of vanet to cloud.
Dynamically Re tasking Sensor Network
Prof. Olariu has expounded the ALERT method towards Dynamically Re tasking Sensor Network. In this routine he consigned the capability to each sensor and estimates the Capability Envelope (CE).
In this discourse the speaker endorses a vision of a sensor network system, where sensors dynamically organize into a high-level system consisting of multiple sensor networks that cooperate to provide data, offer services and perform functions in support of embryonic requirements.
The speaker told that energy consumed to transmit 1 bit of information to 10 meters equal to energy consumed in 100 ALU operations and also focuses the behaviorism of sensor network on psychological aspects.
The re-task-able sensor system consists of independently deployed sensor network to cooperate in the task execution operation. The formation of sensor may be considered as task driven with multi- dimensional considerations. In detect fire activity -the various dimensions are high temp,low humidity,low pressure and smoke yes.
It is also possible to develop some micro level biological nano molecular sensors in the size of our hair , which can be injected into the human body to treat the infected blood cells. so here we conclude that the sensor has a good blessing in medical health care applications.
