The concept of peer-to-peer mobile networks reflects on tactical network. This approach helps mobile nodes to scatter anywhere in the network and it also provide additional support for the MANET in terms of data distribution. This paper provides the result of such approach in terms of network cluster formation with secure node proximity within the boundary. This proximity paradigm will enhance the performance of network by avoid wide scattering of mobile nodes beyond the networks zone. This paper works in NS2 mobility package. The result also incorporates AODV routing protocol with IEEE 802.11 MAC for wireless network to improve network performance using mobile node proximity in conjunction with the previous work indicating the network performance degradation with these configuration.
