Abstract:
A method of providing a multicast service announcement using a hypertext transfer protocol for sending a service announcement from an announcement server to at least one receiving node, the receiving node communicating only with said announcement server to access said service announcement. The announcement server periodically checks for said signaling message from said sending node. The said hypertext transfer protocol announcement is able to communicate with a real-time transport protocol associated with multimedia streams.
Abstract:
The present invention relates to a method for use in managing at least two sensor nodes in a wireless sensor network comprising the step of scheduling the active and sleeping time for the sensor node based on the type of traffic at said sensor nodes; characterized in that, the scheduling the active and sleeping time step further comprising the steps of determining the type of traffic threshold as low (LA) active or high active (HA) determining the status of nodes based on the traffic threshold, reducing the active time of at least one of the nodes from normal active to low active when traffic is low and increasing the active time of at least one of the nodes from normal active to high active when traffic is high. The node is maintained at Normal active time if the traffic is determined as normal.

Abstract:
The present invention discloses a method for use in managing frequency channel based on at least one wireless communication standard in a wireless communication device; whereby the main component is to create groups based on the channel frequencies of the wireless standards provided on the user's device. Based on the groups created, a table is constructed so as to enable selection of frequency channel and verifying link quality, thus avoiding frequency interference.
Abstract:
A method of routing communication on-the-go in a wireless mobile network comprising of a plurality of mobile sensor nodes is disclosed. The method comprises enabling each node to gather information on its neighbouring nodes and store the information in the nodes' Neighbour List Table comprising neighbouring nodes' addresses, hop distance and intermediate neighbours' address. The information gathered may then be shared amongst neighbouring nodes. Using the gathered and/or shared information, a route to a destination node is determined. The route determining step is considered within a predetermined maximum number of hops through the neighbouring nodes. If communication link to the destination is broken, the gathered and/or shared information may be optionally updated. Next, a message received at said each node is determined whether it is destined for itself or to be onwardly routed to next neighbouring node. After this determination, the message is sent to the destination or intermediate node.
Abstract:
A method of optimizing the quality of multicast services over a wireless network by dynamically controlling a broadcast rate, comprising: suppressing an automatic rate fallback protocol so that a broadcast data rate is not limited to the base data rate; transmitting a multicast data stream from an access point to a plurality of nodes; detecting if there is any data loss in the said multicast data stream; and lowering the data rate for each node incrementally if there is any data loss, until the data loss reaches an acceptable level or until the said minimum rate is reached, whichever happens first.

Abstract:
The present invention provides a method and system for representation of Internet Protocol version 6 (IPv6) addresses in a more readable and manageable form, which can be easily remembered. In one embodiment a logical American Standard Code for Information Interchange (ASCII codes) string is selected to denote a node, which is converted into hexadecimal values and appended to the network address so as to form the IP v6 address. The IP v6 address in the ASCII form is more readable and manageable and therefore easy to remember.
