There are currently, many bearer technologies available (Wireline, WLAN, GSM, GPRS, UMTS, etc.) that modern communication devices can use to connect to the Internet. Mobile IP enables such devices to use any of these bearer technologies even while roaming between them and without breaking ongoing communications. However, Mobile IP does not provide...

Telecommunications advances have created the need for a high speed, ubiquitous network capable of catering for diverse application domains. This Next Generation or 4G network can be achieved through the interworking of several existing architectures to form a seamless global network. An important issue involved in interworking is vertical handover....
Wireless local area networks (WLANs) are providing the most economical means of internet access. However, their access is very much limited. They can be deployed in a large scale by integrating them with cellular networks such as universal mobile telecommunication system (UMTS); general packet radio services (GPRS) etc. A seamless roaming between t...
This paper presents an efficient method of vertical handoff from UMTS to Wireless LAN (WLAN) and vice versa in a loose coupling architecture. When a mobile terminal (MT) moves from UMTS to WLAN hotspot, it performs mobile IP (MIP) registration with home agent (HA). Subsequently, HA needs to perform location update operation in UMTS network to make...

... This behaviour is not supported by Mobile IP. Filters for Mobile IP Bindings [4], [5], [18] is a protocol extension of Mobile IP that enables mobile nodes to attach one or more filter definitions to Mobile IP signalling during registration. Flows that match a filter will be processed as defined by the control information of the filter. ...
... Filters for Mobile IP Bindings [4], [5], [18] enables mobile nodes to associate one or more filters with mobility bindings during their establishment (registration, binding update). These mobility bindings will have to refer to the same home IP address. ...
Mobile IP is the dominant Internet standard for the provision of Internet mobility support. However, Mobile IP does not provide any considerations for simultaneous use of multiple points of attachment. This feature is considered very important for Internet real-time communications. Filters for Mobile IP Bindings is a protocol extension of Mobile IP that allows mobile nodes to associate filters with simultaneous bindings for a single home IP address. Flows that match a filter are tunnelled to the point of attachment indicated by the binding. In that way load balancing is achieved. This paper experimentally evaluates load balancing of UDP flows in an experimental testbed. It is determined that during load balancing all flows demonstrated shorter interpacket delays, increased throughput and no packet loss.
Information is one of the key ingredients in the success of any industry. Having information and sending information at the right time and at the right place makes this success. Wearable computing and wireless communication technologies have brought up an informational environment that can be character- ized as anytime-anywhere, which is able to enhance productivity. As a productivity improving element, wear- able computing and wireless communications have reached a state where they can play a major role in the civil construction industry. Workers of different sections of the civil construction operations can use this envi- ronment for tasks such as sharing knowledge between different types of workers when required, updating in- formation like material usage, tasks to be done, presenting needed information at appropriate times and pro- viding guidance and assistance by using multimedia and computer supported cooperative work (CSCW) when required. This paper is about a set of wireless communication technologies, namely Mobile IP and Ad-hoc networking that is considered as a key enabler of this environment. It provides detailed scenarios of how these technologies can be used and the technical details of these technologies.
