Abstract: Resources share and protection are one of key problems needed to solve on mobile ad-hoc networks (MANET).A dynamic paths quorum system on MANET was proposed by making use of the model of voronoi diagram and the idea of quorum system. The construction algorithm of dynamic paths quorum was designed. Based on the dynamic paths quorum system on MANET, a distributed access control mechanism was given and the protocols, such as node authentication, network resources authorization and rights management, were described in detail. Compared with traditional access control mechanism grounded on single node in MANET, the distributed access control mechanism grounded on more nodes, i. e. a quorum nodes, has higher availability and greater capability to withstand attack. It can improve the level of resources share and protection on MANET observably.
