Segmented File Sharing with Recursive Epidemic Placement Policy for Reliability in Mobile Peer-to-Peer Devices

Current approaches for tuning the energy conservation do not take into consideration the storage requirements of each device, the traffic and channel data rate as well as parameters concerning the caching activity for packet forwarding. In this work, an evaluation scheme is proposed based on each node's self-scheduling energy management. This scheme is associating crucial metrics of an ad-hoc wireless host with the remaining capacity units of each device, communicating via asymmetrical wireless links. Promiscuous caching is used in the ad-hoc based connectivity scenario where the-so called-promiscuous caching threshold parameter is introduced in order to bound the associated mobility with storage/capacity and traffic characteristics and figure out a suitable pattern for optimal energy conservation. Through experimental simulation, the proposed energy management scheme is thoroughly evaluated in order to meet the parameters' values where the optimal energy conservation is achieved.

“…Some of the mentioned above problems could be faced using a similar architecture with [1,14] where the idea of Infostation [1] is adopted in a mobility based framework. In [14] the replication scheme comprises of a hybridized version of the static Infostation concept, which structures a layered tree-based scheme using a purely mobile Infostation concept.…”

“…Thus proper information dissemination for specialized services is made through advertisements, which can then be used by the receivers to request and use some other services being provided locally. It is likely that lightweight infrastructure (mobile Infostations [1]) is deployed to "inject" data in the Mobile Ad-hoc Network (MANet) from time to time. Some examples can be found at the dissemination of timetables for local transportation or particular menus of restaurants, etc.…”

Dispersed information diffusion with level and schema-based coordination in mobile peer to peer networks

2007

Cluster Comput

Several open ended issues for high resource availability in mobile peer to peer networks have been examined in the recent past. Different approaches were conducted for supporting information distribution and availability, through guided or unguided packet diffusion. The majority of the recently proposed approaches try to benefit from the spatial characteristics of the dynamically varying topologies. In this work a directed information diffusion scheme is examined using a level and schema-based coordination, applied in mobile peer to peer networks. The prioritization degree of any requested advert is modeled and enables directed prioritized diffusions to end mobile users that are traversing a certain geographic region (location based advertisements). The proposed method is robust in disseminating redundant messages to users while maintaining connectivity through Gradual Energy Tree-based (GET) configuration. Simulation is performed for the examination and performance evaluation of the proposed scheme, taking into account the modeled prioritization as well as the diffusion accuracy by using the Hierarchical and Non-hierarchical GET configuration.

Real‐time performance evaluation of asynchronous time division traffic‐aware and delay‐tolerant scheme in ad hoc sensor networks

SUMMARYWireless infrastructureless networks demand high resource availability with respect to the progressively decreasing energy consumption. A variety of new applications with different service requirements demand fairness to the service provision and classification, and reliability in an end-to-end manner. High-priority packets are delivered within a hard time delay bound whereas improper power management in wireless networks can substantially degrade the throughput and increase the overall energy consumed. In this work a new scheme is being proposed and evaluated in real time using a state-based layered oriented architecture for energy conservation (EC). The proposed scheme uses the node's self-tuning scheme, where each node is assigned with a dissimilar sleep and wake time, based on traffic that is destined for each node. This approach is based on stream's characteristics with respect to different caching behavioral and storagecapacity characteristics, and considers a model concerning the layered connectivity characteristics for enabling the EC mechanism. EC characteristics are modeled and through the designed tiered architecture the estimated metrics of the scheme can be bounded and tuned into certain regulated values. The real-time evaluation results were extracted by using dynamically moving and statically located sensor nodes. A performance comparison is done with respect to different data traffic priority classifications following a real-time asymmetrical transmission channel. Results have shown the scheme's efficiency in conserving energy while the topology configuration changes with time.
