Abstract:
The present invention relates to a method of managing allocation of multiple frequency channels (15) in conjunctions with time slots (25) by each of the wireless node (10) so that each of these wireless nodes (10) can communicate with each of its neighboring wireless nodes (10) based on a specific frequency channel (15) that has been allocated there between at a specifically assigned time slot (25), and thereby prevents the other neighboring wireless nodes (10) from any potential interference during the transmission.
Abstract:
The present invention relates to a system and method for managing the sleeping mode of wireless sensor nodes (110) in a wireless sensor network for managing sleeping schedule of the wireless sensor nodes (110) during an event or crisis. The wireless sensor network comprises of at least one gateway and a plurality of wireless sensor node (110), wherein each wireless sensor node (100) includes a critical stage management module (111) and sleeping schedule management module (112) for managing sleeping mode during an event or crisis.
Abstract:
Described herein is an authentication method that enables a new node (400) to join a wireless sensor network, which comprises a plurality of authenticating nodes (200) that previously has joined the wireless sensor network in a proper network configured security setup, by having the new node (400) and each authenticating node (200) to mutually authenticate each other. In general, the new node (400) requests to join the wireless sensor network and thereby instigating each authenticating node (200) that is nearby to the new node (400) to authenticate the new node (400). Once the new node (400) has been successfully authenticated, the new node (400) will proceed to authenticate each authenticating node (200) that is involved in the authentication process. Thereafter, the new node (400) is allowed to join the wireless sensor network, provided that each authenticating node (200) has also been successfully authenticated by the new node (400).
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:
Described herein is a method that enables an IP device (200) that is capable of IP communication and at least one Internet of Things (loT) device (100) that is not capable of IP communication to communicate with each other in IP manner. Generally, the method works by providing the loT device (100) with virtual IP services, specifically to allocate and link the loT device (100) with a virtual IP address, making the loT device (100) to be virtually IP addressable and identifiable via the allocated virtual IP address. Also described herein is a system for executing the aforesaid method.
Abstract:
The present invention relates to a system and method of an architecture framework incorporating objects of loT. The architecture framework is characterized by: a first horizontal tier, comprising a communication protocol (101); a second horizontal tier, comprising a service protocol (200); wherein the second horizontal tier further comprises: a first vertical tier comprising service consumer (210); a second vertical tier comprising a service provider (220); a third vertical tier comprising a service broker (230); and a forth vertical tier comprising an object provider (240). The method for providing the architecture framework characterized by the steps of: creating service abstraction from a plurality of objects (11); defining the service abstraction into object abstraction to be advertised (12); authenticating the object abstraction and the respective service provider (220) and service abstraction (13); providing a request from the service consumer (210) to access the service abstraction (14); authenticating the service consumer (210) and the request (15); generating a certificate of the service abstraction to the service provider (220) and service consumer (210) (16); forwarding the service abstraction to the service consumer (210) (17); and validating the service abstraction (18).
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.
