Caching popular contents at base stations (BSs) has been regarded as an effective approach to alleviate the backhaul load and to improve the quality of service. To meet the explosive data traffic demand and to save energy consumption, energy efficiency (EE) has become an extremely important performance index for the 5th generation (5G) cellular networks. In general, there are two ways for improving the EE for caching, that is, improving the cache-hit rate and optimizing the cache size. In this work, we investigate the energy efficient caching problem in backhaul-aware cellular networks jointly considering these two approaches. Note that most existing works are based on the assumption that the content catalog and popularity are static. However, in practice, content popularity is dynamic. To timely estimate the dynamic content popularity, we propose a method based on shot noise model (SNM). Then we propose a distributed caching policy to improve the cache-hit rate in such a dynamic environment. Furthermore, we analyze the tradeoff between energy efficiency and cache capacity for which an optimization is formulated. We prove its convexity and derive a closed-form optimal cache capacity for maximizing the EE. Simulation results validate the proposed scheme and show that EE can be improved with appropriate choice of cache capacity.

“…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.…”

Wireless Networking is a technology in which number of mobile nodes can communicate with each other directly or indirectly through wireless links. A sensor network is composed of a large number of sensor nodes and a sink. In the wireless sensor networks the main problem is limited battery life used by sensor nodes because the size of sensor nodes is small so constraints are there like battery size, processor, storage for data, these all are small as sensor nodes Routing protocols of sensor networks are dependable for handles the routes in the networks. This paper surveys current routing protocols for sensor networks and present a categorization for the various approaches pursued and contrast their strength and constraint.
