WTA Architecture
Browsing the web using the WML browser is only one application for a handheld device user. Say a user still wants to make phone calls and access all the features…
Wireless transaction protocol (WTP)
The wireless transaction protocol (WTP) is on top of either WDP or, if security is required, WTLS (WAP Forum, 2000d). WTP has been designed to run on very thin clients,…
Wireless Transport Layer Security (WTLS)
If requested by an application, a security service, the wireless transport layer security (WTLS), can be integrated into the WAP architecture on top of WDP as specified in (WAP Forum, 2000c). WTLS can…
Wireless Datagram Protocol (WDP)
The Wireless Datagram Protocol (WDP) operates on top of many different bearer services capable of carrying data. At the T-SAP WDP offers a consistent datagram transport service independent of the underlying…
WAP-ARCHITECTURE
The above Figure gives an overview of the WAP architecture, its protocols and components, and compares this architecture with the typical internet architecture when using the World Wide Web. This…
MOBILE TCP
The M-TCP (mobile TCP)1 approach has the same goals as I-TCP and snooping TCP: to prevent the sender window from shrinking if bit errors or disconnection but not congestion cause current…
MANET vs VANET
MANET is the short form of Mobile AdHoc Network. In ad-hoc networks all the nodes are mobile in nature and hence they can be interfaced dynamically in arbitrary fashion. As we know…
VEHICULAR ADHOC NETWORKS (VANET)
Vehicular Ad hoc Network (VANET), a subclass of mobile Ad Hoc networks (MANETs), is a promising approach for future intelligent transportation system (ITS). These networks have no fixed infrastructure and…
Overview of Multicast Routing Protocols
Here is a brief overview of the multicast routing protocols that have been developed for the Internet. Distance Vector Multicast Routing Protocol (DVMRP):5 DVMRP was the first multicast routing protocol developed for…
MULTICAST IN THE INTERNET
Some applications require data to be delivered from a sender to multiple receivers. Examples of such applications include audio and video broadcasts, real-time delivery of stock quotes, and teleconferencing applications.…
