We have developed a layered hierarchy of internetworking and intranetworking levels of management called a MetaNet. Management at the internetwork level is conducted in a manner that models each network abstractly. At the intranetwork level management accounts for the detailed implementation and organizational characteristics of each network. The paper explores how to employ these layers to cooperatively satisfy end-to-end requests for connectivity with an associated QoS. In addition, we explore negotiation between the inter- and intranetwork levels of management and brokering of QoS by the internetwork level among the intranetwork level managers.","PeriodicalId":136537,"journal":{"name":"2001 MILCOM Proceedings Communications for Network-Centric Operations: Creating the Information Force (Cat.

The channel model includes the near-field wave propagation between the transmitter antenna and the scattering blades. The channel model is used to examine the performance of different diversity techniques, namely, the transmitter diversity, multicarrier frequency hopping (MCFH) and the fast frequency hopping (FFH), in view of the antenna polarization and relative strength of the direct path and the scattering component from the rotating blades.","PeriodicalId":136537,"journal":{"name":"2001 MILCOM Proceedings Communications for Network-Centric Operations: Creating the Information Force (Cat.

By an overloaded array system, we mean that the number of desired signals exceeds the number of distinct antenna elements, often by a significant amount. We evaluate the performance of the proposed signal extraction method through the use of bit error rate (BER) simulation. The simulation results show that the new signal extraction method can increase the number of users that can be supported in an airborne communication environment. We also evaluate the effects of directional antenna patterns on the performance of the proposed signal extraction method. Performance results for an 8 element antenna array show that the proposed signal extraction method with a 60/spl deg/ half-power beam width (HPBW) directional pattern can support up to 16 users (twice as many as number of antenna elements) and a 30/spl deg/ HPBW directional pattern can support up to 24 users (three times as many as number of antenna elements).","PeriodicalId":136537,"journal":{"name":"2001 MILCOM Proceedings Communications for Network-Centric Operations: Creating the Information Force (Cat.

For a given alphabet size, a Hermitian code has a much longer block length than a Reed-Solomon code. This and other considerations suggest that Hermitian codes may be superior for certain applications. Analytical results are developed for the evaluation of the packet error probability for FH transmissions using Hermitian coding. We find there are several situations for which Hermitian codes provide much lower packet error probabilities than can be obtained with Reed-Solomon codes. In general, as the code rate decreases or the symbol alphabet size increases, the relative performance of Hermitian codes improves with respect to Reed-Solomon codes. Performance evaluations are presented for an additive white Gaussian noise channel and for a catastrophic partial-band interference channel, and the packet error probability is evaluated for both errors-only and errors-and-erasures decoding.","PeriodicalId":136537,"journal":{"name":"2001 MILCOM Proceedings Communications for Network-Centric Operations: Creating the Information Force (Cat.

We present our approach to configuring and reconfiguring an entire network domain, possibly consisting of tens of thousands of hosts and routers, based on a new dynamical configuration distribution protocol (DCDP). DCDP automatically distributes address-pools and other IP configuration information to every subnet in a domain, where a subnet configuration protocol can configure each node in a subnet. This paper describes the first implementation of DCDP and shows how, with the subnet configuration protocol DRCP, it rapidly configured IP addresses to Linux hosts and routers.","PeriodicalId":136537,"journal":{"name":"2001 MILCOM Proceedings Communications for Network-Centric Operations: Creating the Information Force (Cat.

Positioning range extension gateways in mobile ad hoc wireless networks to improve connectivity and throughput 在移动自组织无线网络中定位范围扩展网关,以提高连接性和吞吐量

Katz","doi":"10.1109/MILCOM.2001.985814","DOIUrl":"https://doi.org/10.1109/MILCOM.2001.985814","url":null,"abstract":"The dynamic nature of a mobile ad hoc network (MANET) may result in a cluster of nodes being isolated from the remaining network, especially when deployed in a terrain with blockages. In order to facilitate scalability and to provide connectivity between partitions that might occur in wireless networks as a consequence of mobility, we can envision a 'range extension' network that consists of airborne communication platforms, or geostationary/low-Earth-orbit satellites. These airborne/satellite nodes maintain communication links with specific 'gateway' nodes among the mobile ground nodes. To communicate with a node that is geographically distant or belongs to a different network partition, an ad hoc node can relay its data packets through an appropriate mobile gateway and via the range extension network. If we envision that the MANET is divided into different groups and a mobile gateway is deployed for each such group, an objective then is to determine the trajectory of the mobile gateway to best serve the ad hoc group to which it belongs, in terms of network performance metrics such as throughput and latency. In this paper, this problem of computing the optimal position for a gateway is reduced to a linear optimization problem by means of some simplifying but realistic assumptions. We suggest methods that may be deployed to enable the gateway to follow this optimal trajectory as closely as possible (within the practical constraints imposed by its velocity and maneuverability). Simulation results for various scenarios show a 10-15% improvement in the throughput and latency, per gateway domain, if a gateway has a dynamic trajectory whose locus follows the computed optimal position, as compared to a gateway that is statically placed at a regular position, or to a gateway that has a random trajectory.","PeriodicalId":136537,"journal":{"name":"2001 MILCOM Proceedings Communications for Network-Centric Operations: Creating the Information Force (Cat.

Traffic characteristics of data users can be characterized by burstiness and asymmetricity. Data traffic such as in Internet web browsing applications show asymmetric characteristics that cause a relatively heavy load on the forward link. Bursty data can drive the system into a situation wherein available CDMA codes are depleted even when there is enough margin of signal-to-interference ratio (SIR) to accept a new call. Thus, we propose a new call admission control (CAC) scheme on the CDMA forward link that reserves both some codes and interference margin for handoff calls. With the proposed CAC scheme, we construct a Markovian model for voice and data calls (two classes) in progress. The proposed scheme is compared with the conventional scheme that reserves interference margin only. Numerical results show that the proposed scheme is more efficient in accommodating calls under a given set of constraints.","PeriodicalId":136537,"journal":{"name":"2001 MILCOM Proceedings Communications for Network-Centric Operations: Creating the Information Force (Cat.
