Challenges face the Internet Architecture in order to scale to a greater number of users while providing a suite of increasingly essential functionality, such as multi-homing, traffic engineering, mobility, localised addressing and end-to-end packet-level security. Such functions have been designed and implemented mainly in isolation and retrofitted to the original Internet architecture. The resulting...
Traditional Internet faces many challenges, ranging from security threats, routing scaling problems to inadequate support for mobility, multihoming and traffic engineering. This paper proposes a clean-state network-based architecture, named identifier separating and mapping architecture (ISMA), to solve these problems. The key design concepts of ISMA include separating customer networks from the core...
One particular challenging environment for multicast is a mobile ad-hoc network (MANET). Existing studies show that tree-based and mesh based on-demand protocols are not necessarily the best choice, since associated overhead will be more. Several algorithms based on the ant colony optimization (ACO) approach minimizes the cost of the tree under multiple constraints. These algorithms treat the traffic...
