Shortest link scheduling (SLS) is one of the most fundamental problems in wireless networks. Almost all of the state-of-the-art approximation algorithms for SLS in wireless networks are resorted to the ellipsoid method for linear programming exclusively. However, the ellipsoid method can require an inordinate amount of running time and memory even for a(More)
Roaming across two adjacent access networks poses a challenging issue in providing continuity services for end-users. FMIPv6, a cross layer handover scheme proposed by the IETF, requires the timely link layer (L2) trigger to invoke the handover protocols of upper layer, the specified handover procedures hence can be completed before terminating the current(More)
This paper presents a comparative study of collectives of term weighting methods for extractive speech summarization of Mandarin Presentation Speech. The summarization process can be considered as a binary classification process. The collectives of different term weighting methods can provide better summarization performance than each of them with the same(More)
In data-centric and application-oriented Wireless Sensor Network, effective energy-saving is an eternal theme, while in the scenarios deployed multiple flows, the network resource competition directly influences the whole network performance. To address this issue, a cooperative routing scheme is developed by comprehensively taking both the routing(More)
