This paper examines whether the Peter Principle operates in a large hierarchical financial sector firm. We use a method that allows for variation in optimal effort over stages in the hierarchy, which suggests, at least in the organisation we study, that the mean fall in performance actually understates the effect of the Peter Principle.

Wireless sensor networks (WSNs) are resource constrained. Energy is one of the most important resources in such networks. Therefore, optimal use of energy is necessary. A novel energy-efficient routing protocol is proposed for WSNs. The protocol is reliable in terms of data delivery at the base station (BS). Mobility in sensor nodes and in the BS is considered. The proposed protocol is hierarch...

The paper proposes two alternative bandwidth allocation schemes suited for the Ka-band satellite environment. The aim is to provide a control mechanism to compensate rain fade. The main idea is considering the effect of the attenuation as a reduction of the bandwidth 'seen' by a single land station and using a supplementary portion of bandwidth to guarantee a rain margin. One of the earth stati...
