With the rapid growth of next generation optical network, in order to meet this demand to the rising routing technology, IETF Path Computation Element (PCE) Working Group defines the MPLS/GMPLS network structure based on PCE, PCE technology has gradually become the key technology of the next generation optical network because of its independent and flexible architecture, especially in the GMPLS-based...
Capacity limitation is one of the fundamental issues in wireless mesh networks. The aggregate capacity can be increased by equipping each mesh router with multiple radios tuned into distinct frequency channels. However, most past research efforts that attempt to exploit multiple channels assume orthogonal channels of fixed pre-determined width, which prohibits the further effective use of spectrum...
In third-generation (3G) wireless data networks, providing service to low data-rate users is required for maintaining fairness, but at the cost of reducing the cell's aggregate throughput. In this paper, we propose the unified cellular and ad hoc network (UCAN) architecture for enhancing cell throughput while maintaining fairness. In UCAN, a mobile client has both 3G interface and IEEE 802.11 -based...
