Mobility Management in P2P Wireless Networks March 17, 2006
Mobility management in wireless networks is an important task in order to keep connectivity with roaming users at anytime. Mobile IP1, which is a standard proposed by the Internet Engineering Task Force (IETF), can serve as the global mobility management in the future heterogeneous wireless networks.
Mobile IP uses the home agent (HA) and foreign agent (FA) to maintain the mobility of a mobile node (MN). The HA maintains the address binding of an MN, and the address binding is a mapping between the permanent home address to the care-of address (CoA) temporally borrowed from an FA.
Mobile IP suffers from several …

The purpose of JXTA-J2ME is to provide a JXTA compatible functionalities on constrained devices using the Connected Limited Device Configuration (CLDC) and the Mobile Information Device Profile 2.0 (MIDP). The range of devices include the smart phones to PDAs. Using JXTA for J2ME, any MIDP device will be able to participate in P2P activities with other devices within the JXTA network.The JXTA-J2ME (JXME) project hosts the reference implementation of the JXTA protocols for J2ME. The first JXME (proxy based) implementation was done in J2ME/MIDP 1.0 to implement a compatible JXTA implementation for J2ME.Features supported in JXTA-JXME:
1. Discovery

Voice calls must be able to recruit data channels, and vice versa. That way, an agent could attach an IM session to your voice call and push you the URL in real-time chat. It might even be appropriate to extend the data session with screen sharing, so the agent can watch and assist. If things still don’t work out and the whole matter must be referred to someone else, you’d like to be able to initiate voice or data communication — or both — in a context-preserving way.

JXTA technology enables a world in which billions of network services, all addressable on the Internet, will be able to discover and interact with each other in an ad hoc and decentralized manner through a multitude of virtual Internet domains.The main focus of JXTA technology has been to build a highly scalable and resilient Internet-scale infrastructure. For instance, JXTA technology’s decentralized P2P routing protocols provide the foundation to build a highly scalable search engine in which search queries get routed dynamically to the end peers that published the information. This is the inverse of Google’s indexing model, in which …
