Today P2P (Peer-to-Peer) networks are gaining popularity for sharing the contents. Due to massive spreading of Internet, these networks are also growing fast. MP2P (Mobile P2P) networks are attracting many users due to increase in the Internet-based mobile applications. These networks suffer from many challenges which are not considered for analysis and modelling adequately. We focus on few challenges like mobility of users, churn rate, intermittent bandwidth, shorter life span of mobile nodes, stabilization of finger table, etc. in this paper. We analytically analyse these challenges and define the effects of different parameters over the performance. Traditional P2P protocols are designed for wired networks and when these are implemented for mobile networks then mobility effect of users adds more challenge for researchers. We select two types of mobility models namely FF (Fluid Flow) and RWP (Random Waypoint) models to model the users’ mobility. The churn rate of the mobile nodes makes network overlay management and content searching more difficult in MP2P networks. We select finger table-based protocols which are widely deployed in the P2P networks. But these protocols can’t perform well in the mobile P2P networks due to mobility of the users. The mobility of the users and churn rate of the mobile nodes create failure in lookup of finger table and induce more cost to update the finger table. We consider these challenges and quantify the failure rate of mobile nodes, life span of mobile nodes, available bandwidth, cost of stabilization of finger table per node, etc. in this proposal. The proposed model is useful for modelling the performance of MP2P networks performance in various wireless environments like Mobile Ad hoc Networks (MANETs), Wireless Mesh Networks (WMNs), Wireless Sensor Networks (WSNs), Vehicular Ad hoc Networks (VANETs), Wireless LAN (WLAN), Wireless MAN (WMAN), etc.

今天，P2P（点对点）网络因共享内容而变得越来越流行。由于Internet的广泛传播，这些网络也在迅速发展。由于基于Internet的移动应用程序的增加，MP2P（移动P2P）网络吸引了许多用户。这些网络遭受许多挑战，这些挑战没有被适当地分析和建模。在本文中，我们重点关注一些挑战，例如用户的移动性，流失率，间歇带宽，移动节点的寿命较短，手指表的稳定性等。我们分析分析这些挑战，并定义不同参数对性能的影响。传统的P2P协议是为有线网络设计的，当将这些P2P协议用于移动网络时，用户的移动性效应给研究人员带来了更大的挑战。我们选择两种类型的移动性模型，即FF（流体流）和RWP（随机航点）模型来对用户的移动性进行建模。移动节点的客户流失率使MP2P网络中的网络覆盖管理和内容搜索更加困难。我们选择在P2P网络中广泛部署的基于手指表的协议。但是由于用户的移动性，这些协议在移动P2P网络中不能很好地执行。用户的移动性和移动节点的流失率在查找手指表时造成失败，并导致更新手指表的成本增加。我们考虑了这些挑战，并在此提案中量化了移动节点的故障率，移动节点的寿命，可用带宽，每个节点的手指表的稳定成本等。
