ABSTRACT
P2P computing model has full-distributed characteristic and self-organization
characteristic,has been widely used in many fileds. With the gradual establishment of
network infrastructure and the mature of mobile communication technology,and the
rapid development of mobile computing devices,the limitation of compute and
standby capacity has been settled gradually,data format also became increasingly
unified.Therefore,make use of laptops, personal digital assistant,mobile phone in
order to complete share,communication,collaboration between mobile users in mobile
applications .P2P computing model has began to expand to mobile devices and mobile
netword filed in academic research and industrial development.However,Mobile
network is a constrained-resource system, construct P2P network in mobile
environment exists some of its inherent flaws and features,such as shortage of energy
and resources of mobile computing devices, relatively weak in communication
capacity,frequently network change,and interruption of the unpredictability of
network connection etc,these brought some difficulties to build P2P network in
mobile environment..
Research of Network topolosy,Resources search strategies are critical technical in
mobile P2P network,are also currently the focus of academic reseach.Topology of
mobile P2P network not only need to consider interoperability and integration of
heterogeneous network ,but also must be independent in variety of specific
applications,an should ensure network scalability.Equally the strategy of resource
search is a core problem of P2P application,how to fast respond to user request by
effective means,this related to the efficiency and performance of P2P applications.To
these issues,this essay commit itself to research of these aspects,trying to make some
contribution to topology generation method in P2P network and strategy of resource
research.
First,The paper introduces the concept of P2P ,the concept of mobile P2P network
and key technologies.Second,Analysis currently topology generation technology and
propose a method of topology generation in mobile P2P network.Last,achieve a visual
prototype system,and use the system can be conveniently to analysis and compare the
performance of algorithm.
