Effective Cache based Policies in Wireless Sensor Networks: A Survey

Abstract

The sensor nodes in Wireless Sensor Network are battery powered devices which consumes energy during data transmission, processing, etc. The critical task in WSN is to deal with optimizing power consumption. One possible way to minimize power consumption is by the use of caching the data. Generally data transmission in WSN consumes more energy than processing, so it is good to utilize the benefits of caching so that data access can be made faster. Caching, if used efficiently, could reduce overall network traffic and hence bandwidth can be optimally utilized. In this paper we are reviewing the various data caching techniques in WSNs. This paper aims at future research work and provide researcher with helpful guidelines.

Energy Efficient Caching in Backhaul‐Aware Cellular Networks with Dynamic Content Popularity

“…, }, and the size of each content in the catalog has a length of ( ) Mbytes. According to the description of Section 3, we can predict the content popularity, and the instantaneous popularity follows the Zipf distribution [31]. Each user requests a content from the content catalog , and the probability of requesting the th content is…”

Simulation Based Analysis of Cluster-Based Protocol in Wireless Sensor Network

“…The wireless standard is of infrared, radio frequency that having no wired tie friendly. So the sensor nodes are deployed in a random conduct and it make ad-hoc network because they can discuss themselves [1]. If the node is unable to converse with other nodes of the network through a direct link, it means the node is out of range.…”

A Comparative Review on Routing Protocols in Wireless Sensor Networks

“…The wireless medium is of infrared, radio frequency that having no wired connection attached. So the sensor nodes are deployed in a random manner and it make ad-hoc network because they can communicate themselves [1]. If node is unable to communicate with other nodes of the network through direct link, it means node is out of range.…”
