Patent number: 8490175Abstract: A security method and system for Layer Independent Passive Clustering (LIPC) is presented. The inventive method and system maintains the states in the LIPC cluster formation protocol while adding a ‘Trusworthy’ event to each state and provides a methodology that depends on the state of the transmitting node to quantify Trustworthy and derive a Trust Confidence Value (TCV) to represent the level of confidence in quantifying ‘Trustworthy’. The invention dynamically computes a degree of trustworthiness for each participating network node and eliminates nodes from participating in the PC cluster formation protocol and packet forwarding if they do not meet established trust metrics. The security solution can also apply to PC-based Mobile Ad hoc Networks (MANETs). The novel system and method applies a multidimensional set of security algorithms to protect the LIPC cluster formation protocol from malicious attacks that compromise cluster formation and secure routing.Type: GrantFiled: December 6, 2011Date of Patent: July 16, 2013Assignee: Telcordia Technologies, Inc.Inventors: Melbourne Barton, Taek Jin Kwon

Patent number: 7433297Abstract: A wireless Internet access system and method supports the transmission and reception of multiple types of traffic between mobile subscriber units and existing networks. A frame structure is used that can support the transmission of multiple types of traffic and adapt to changes in the traffic types needed and the amount of data for a particular traffic type. In addition, data transmission is performed using orthogonal frequency division multiplexing and differential phase shift keying to avoid intersymbol interference. Receiving units in the mobile subscriber units and existing networks include antenna arrays to provide a multipath transmission.Type: GrantFiled: December 27, 2004Date of Patent: October 7, 2008Assignee: Telcordia Technologies, Inc.Inventors: Melbourne Barton, Joseph C.

Publication number: 20040103311Abstract: Secure wireless communications for a mobile host over any wireless interface within a wireless network is provided by a security gateway. The security gateway is situated and configured within the mobile host's home network of the wireless network such that it provides the only point of access between the wireless network and the home network. Additionally, the security gateway is separate and distinct from the mobile host's home agent within the home network. A single tunnel mode security association is established between the mobile host's wireless interface and the security gateway's network interface on the home network. This single tunnel mode security association remains established as the mobile host moves between foreign networks and provides secure wireless communications to the mobile host whether the mobile host is in the home network or the foreign networks.Type: ApplicationFiled: November 27, 2002Publication date: May 27, 2004Inventors: Melbourne Barton, Kuok-Shoong Wong, Mario Joa-Ng, Derek Atkins

Patent number: 6654431Abstract: A highly modular PACS-based system that combines the advantages of Optical Frequency Division Multiplexing (OFDM) and Personal Access Communication System (PACS) with Time Division Multiple Access (TDMA) technology. The system is arranged to support high-speed (higher than the 32 kbps of PACS) wireless access services to fixed and mobile users. For example, nominal user data rates of 32-to-356 kbps are attainable, and ever the higher speed of 768 kbps is possible for short ranges.Type: GrantFiled: December 30, 1999Date of Patent: November 25, 2003Assignee: Telcordia Technologies, Inc.Inventors: Melbourne Barton, Kuok-Shoong Daniel Wong

Publication number: 20020150094Abstract: Hierarchical Level-Based IP Multicasting (HLIM) is a method for the multicasting of data packets from a source to a number of receivers on a network that supports both host and network mobility. In HLIM, IP routers are assigned to hierarchical levels to become hierarchical designated routers. The hierarchical levels also are used to define a scope region in which multicast data packets are to be delivered. Each scope region is associated with a unique root identifier (RID). Scope region information and root identifiers are placed into a multicast address so that multicast packers of data will be distributed to routers and hosts within the scope region. If a host (receiver or source) or sub-network moves out of the scope region but desires to continue receiving multi-cast packets the host can request receipt of such packets from its new parent hierarchical designated router through use of the RID and associated binding point (BPT).Type: ApplicationFiled: October 26, 2001Publication date: October 17, 2002Inventors: Matthew Cheng, John Lee, Melbourne Barton
