In recent years, the skyline operator has received considerable attention in the database research community. This is mainly due to the importance of various skyline results in applications involving multi-criteria decision making. On recently, skyline queries are considered in distributed computing environments e. 3gp; this paper, we exploit the problem of skyline query processing in sensor networks.
Many previous studies investigated efficient approaches to answer skyline queries in a centralized manner. However, those approaches cannot be applied directly to the sensor network environment primarily due to limited power and resource of sensor nodes. Our solution is based 331102 two main ideas: The clustering architecture partitions sensor readings into several clusters.
By using the clustering architecture, we can identify the sensor that stores skyline points 33012 dominate many data points in the early stage of the query processing.
Those skyline points can be used to discard unqualified data points from further examination. The pruning strategy can help to control the amount of query forwarding, limiting the 3hpp of sensors involved and the amount of 3102 transmitted in the network.
We conduct a comprehensive data set of experiments to reveal that SKYSENSOR significantly outperforms other existing methods while processing skyline query in a sensor network. ACM Press, June Technology EDBTpp. ACM Press, May In this thesis, we develop an MPEG based multimedia streaming session handoff mechanism over the 3-tier network environment platform.
In the 3-tier Server-Proxy-Client network architecture, the proxy can provide cached and relayed functions to reduce server workload and distribute streaming traffic. In order to satisfy the characteristics of network heterogeneity and client devices’ diversity, the proxy should provide different qualities of media streaming using scalable video coding.
To achieve network-adaptive and device-adaptive for video streaming, layered proxy 3hpp admission and replacement policies are 3gpl with advances of scalable video coding for the 3-tier Server-Proxy-Client network architecture in this thesis.
The proposed layered cache admission and replacement policies can manage the proxy cache in consideration of the quality-of-service and the video popularity.
In this thesis, ‘ubiquitous streaming’ means that a streaming client is allowed to change the streaming session i from network A to network B, e. In order to achieve ubiquitous streaming over the 3-tier network architecture, a proxy handoff mechanism is designed to make video playback smoother and reduce the user’s waiting time after the session handoff.
In our experiments, we exhibit merits and performance results of the proposed cache admission and replacement mechanism. Additionally, we also analysis the experimental results of the proposed multimedia proxy handoff mechanism.
IMS enables and enhances real-time multimedia mobile services. After media session negotiation, media is sent from end to end. It results in that a certain load occurs in the HSS and a certain procedure delay also occurs.

The tracking techniques play a significant role in wireless sensor network applications, such as troops monitoring and wildlife habitat monitoring. The methodology of recently proposed tracking schemes predicts the object location in the future based on a 331002 model, and then activate nearby sensors to monitor the target periodically. However, existing tracking systems cannot effectively track targets for a long time. This is because in most real-world applications, a target frequently or occasionally moves with different patterns, and accurately predicting the movement of a target needs 3302 moving models, instead of a single model.
Thus, the existing schemes frequently incur target loss, and a great amount of energy is consumed to find back the target. MMOTA can dynamically select the best tracking modules to monitor the target among the multiple predesigned tracking modules in different situations. Next, we derive a Monitoring-Cost Evaluator to evaluate the monitoring cost for the inactive tracking modules, and then design three tracking module selection strategies, including Greedy Strategy, Min-Max Strategy, and Weighted Moving Average Strategy, to select the most effectively tracking module for monitoring the target.
Finally, we conduct a set of comprehensive experiments to compare MMOTA against the existing tracking systems and evaluate the three proposed tracking module selection strategies. The result shows that MMOTA consumes the much less energy for monitoring the target than the existing tracking systems, and saves more than A Survey on Sensor Networks.

The use of edge-disjoint spanning trees for data broadcasting and scattering problem in networks provides a number of advantages, including the increase of bandwidth and fault-tolerance. In this thesis, we elucidate the problem of embedding multiple edge-disjoint spanning trees in locally twisted cubes with the objective of parallel and maximum. Based on a simple concept called Latin square, we develop 3gpo algorithm to construct EDSTs in a locally twisted cubes efficiently.

Compromised nodes are problematic in wireless sensor networks. The packet-dropping attacks and packet-tampering attacks which are made by the compromised node causes the packets of other sensor nodes not being able to relay to the base station timely and correctly.
In this work, a new NWS with tripartite key is proposed. A tripartite key is a key shared among three contiguous nodes: By the support of tripartite key, the watching node in any tripartite key operation can monitor the packets which the forwarding node forwards to the receiving node.
In this paper, we use the method which called Sequence of Games SoG to proof that our tripartite key distribution protocol is secure. After that, we suggest that this neighbor watch system can combine with the quarantine mechanism. By this way, our neighbor watch system can arise its 3gpp further.
