In some cases of insurgency, the combat frontier is contested and erratic, as rebels target cities as their economic prey. In other cases, it is tidy and stable, seemingly representing an equilibrium in which cities are effectively protected from violent non-state actors. What factors account for these differences in the interface urban-based states and rural-based challengers? To explore this question, this book examines two regions representing two dramatically different outcomes. In West Africa (Liberia and Sierra Leone), capital cities became economic targets for rebels, who posed dire threats to the survival of the state. In Maoist India, despite an insurgent ideology aiming to overthrow the state via a strategy of progressive city capture, the combat frontier effectively firewalls cities from Maoist violence. This book argues that trade networks underpinning the economic relationship between rural and urban areas—termed “interstitial economies”—may differ dramatically in their impact on (and response to) the combat frontier. It explains rebel predatory tendencies toward cities as a function of transport networks allowing monopoly profits to be made by urban-based traders. It explains combat frontier delineation as a function of the social structure of the trade networks: hierarchical networks permit elite–elite bargains that cohere the frontier. These factors represent what might be termed respectively the “hardware” and “software” of the rural–urban economic relationship. Of interest to any student of political economy and violence, this book presents new arguments and insights about the relationships between violence and the economy, predation and production, core and periphery.

The detection points are the detection points in the space of network. The properties of detection points include cost effective materials and longer battery capacity. WSN can span variety of applications like sensing of data related to environment entities, detection of enemy vehicles. Lifetime ratio defines the efficiency of the WSN network operation. There are multiple techniques which can help in improvement of Network Lifetime (NL) spanning from transmission nature, data connections, formation of System and time scheduling. This paper provides the analysis of how energy consumption happens and its effect on lifetime ratio. LEACH and CHEF algorithms responsible for hierarchical kind of routing are discussed in detail with simulation results. The parameters used for comparison includes delay, hops, consumption of energy. Non-Hole detection points, Hole detection points, Non-Hole to Hole Ratio, residual energy, routing overhead and throughput.
