On the impact of caching and a model for storage-capacity measurements for energy conservation in asymmetrical wireless devices

Abstract

Traffic and channel-data rate combined with the stream oriented methodology can provide a scheme for offering optimized and guaranteed QoS. In this work a stream oriented modeled scheme is proposed based on each node's selfscheduling energy management. This scheme is taking into account the overall packet loss in order to form the optimal effective -for the end-to-end connection-throughput response. The scheme also -quantitatively-takes into account the asymmetrical nature of wireless links and the caching activity that is used for data revocation in the ad-hoc based connectivity scenario. Through the designed middleware and the architectural layering and through experimental simulation, the proposed energy-aware management scheme is thoroughly evaluated in order to meet the parameters' values where the optimal throughput response for each device/user is achieved.

A tier-based asynchronous scheduling scheme for delay constrained energy efficient connectivity in asymmetrical wireless devices

“…This area which is recognizable by geographical information, allows only one node to be active in the grid while the other nodes turn off their interfaces to conserve energy. In [17] the goal is to turn off nodes without significantly diminishing the capacity or connectivity of the network. The connectivity and forwarding capability as stated in [17], is maintained by keeping the nodes that constitute a backbone infrastructure, in active mode and switching off the other.…”

The connectivity and forwarding capability as stated in [17], is maintained by keeping the nodes that constitute a backbone infrastructure, in active mode and switching off the other. Also a traffic-load history determination in association with battery lifetime has been examined in [7].…”

“…As a part of the already existing work done in [1,3,7,8,[15][16][17] where a combination of history traffic scheme along with an association of the behavioral promiscuous caching characteristics and storage-capacity characteristics, this work proposes an architectural optimization of the previous frameworks by introducing the cross layered two-tier model in order to collaboratively conserve energy. The model measures the validity and effectiveness of the new proposed middleware and controls the mobile interfaces by minimizing the energy consumed on any asymmetrically located wireless link.…”

“…Also the role of a traffic free-layer is of main importance since we can prolong network lifetime as examined in [16,17]. On the other hand the CNL will serve the traffic itself.…”

“…The number of times being in the CNL should be in the range of 0 < n < 2, in order to avoid the saturation of the state of the node N to remain in the same state for prolonged time duration, as shown in [15][16][17]. The number of times being in the CNL is calculated as follows: if the capacity was enough according to C N ≥ C thresshold , at a given time interval (t, T ], then the node N can securely enter the semi-sleep state in order to conserve energy if and only if it follows the optimality principle for the capacity, satisfying the: (3.1) and…”
