Improving Fading-Aware Routing with Circular Cache Layers in Wireless Sensor Networks

Modified Circular Layer Caching in Wireless Sensor Networks

“…The detailed analysis of energy consumption of the proposed scheme and CCL scheme [14] under different scenarios along with the energy savings attained by our proposed scheme is presented in the The amount of savings in energy consumption that can be achieved is application dependent for which caching scheme is used. The applications having TTL associated with data more than 50% and number of sources less than 75% saves considerable amount of energy with the modified caching approach over the CCL [14] scheme.…”

“…The applications having TTL associated with data more than 50% and number of sources less than 75% saves considerable amount of energy with the modified caching approach over the CCL [14] scheme. By considering TTL value as 50% and number of sources as 75% as the best scenario, the energy savings of 56.05% has been achieved by the modified caching scheme.…”

“…Pant et al proposes a caching scheme in which the Concentric Circular layers (CCL) are formed around each sink and the various nodes lying in the layers formed acts as a cumulative cache to store the sensed data [14]. The algorithm used to form the CCLs around the sink, floods a message to all nodes lying at a particular distance from the sink, which forms a cache layer by responding to the message to cache the sensed data.…”

“…Caching of the data in the nodes near the sink or forming the central part of network shows better approach of caching the data [6,7,14]. This paper discusses modified Concentric Circular Layer Caching scheme which uses cooperative caching strategy to cache the data in the nodes surrounding the sink along with the table maintained at each sink.…”
