Abstract In this paper, we consider the problem of power control when nodes are non-homogeneously dispersed in space. In such situations, one seeks to employ per packet power control depending on the source and destination of the packet. This gives rise to a joint problem which involves not only power control but also clustering. We provide three solutions for joint clustering and power control. The first protocol, CLUSTERPOW, aims to increase the network capacity by increasing spatial reuse. We provide a simple and modular architecture to implement CLUSTERPOW at the network layer. The second, Tunnelled CLUSTERPOW, allows a finer optimization by using encapsulation, but we do not know of an efficient way to implement it. The last, MINPOW, whose basic idea is not new, provides an optimal routing solution with respect to the total power consumed in communication. Our contribution includes a clean implementation of MINPOW at the network layer without any physical layer support. We establish that all three protocols ensure that packets ultimately reach their intended destinations. We provide a software architectural framework for our implementation as a network layer protocol. The architecture works with any routing protocol, and can also be used to implement other power control schemes. Details of the implementation in Linux are provided.. 1. Introduction The power control problem is to choose the transmit power level for every packet in a wireless ad hoc network. The per-packet choice is to be guided by several considerations. The choice of transmit power, and thus the range, affects the traffic-carrying capacity of the network, and it was shown in [1] that after taking into consideration the additional relaying burden of using small hops versus the interference caused by long hops, it is optimal to reduce the transmit power level. The choice of power level also affects battery life. In [2], it was shown that for the commonly used propagation path loss attenuation models, low power levels are commensurate with power optimal routing. This was done by showing that the latter necessarily results in planar graphs of power optimal routes, with only nearby nodes exchanging packets. Moreover, power control affects routing since the ranges of the transmitters depend on the transmit power levels. A further factor to be considered is that power control affects packet end-to-end latency. With small power levels, a packet will take a large number of hops which may linearly increase latency due to the packetization delay at each hop. Given this complexity of considerations, how does one i) conceptualize the power control problem, ii) determine how to trade off the multiple objectives of capacity, battery life and latency, and iii) develop a protocol which is modular and elegant enough to work with the OSI architecture? A first cut solution was presented in [2]. A network layer protocol, called COMPOW, was developed which ensured that the transmit power used by all the nodes would converge to a common power level: the lowest power level at which the network is connected. A software architecture was also developed with the requisite properties of modularity and layering. An implementation in the Linux kernel was also provided. When nodes are homogeneously dispersed in space, as in Fig. 1(a), the choice of a common transmit power level has several appealing properties as noted above. However, when nodes are non-homogeneously dispersed as in Fig. 1(b), then the lowest common power level for network connectivity is hostage to the outlying nodes which are far from others. For example, in Fig. 2, all nodes except node F are mutually reachable at 1 mW, i.e., they form a 1 mW cluster, but F is reachable only by using a power level of 100 mW. The COMPOW algorithm, designed to converge to the lowest power level such that the network is connected, will thus converge to 100 mW, even though 1 mW is enough for most communications. Such non-homogeneous scenarios are ripe for clustering. One wishes to group nodes into clusters, with several clusters at power level k forming a cluster at power level k + 1. Such clustering of nodes cannot simply be based on geographical co-ordinates since obstacles and shadowing may prevent two nodes from forming a wireless link, even if they are in close proximity. Power control should also be done in conjunction with routing, since it needs to keep connectivity in mind, which is known only through the existence of routes. Conversely, routing depends on power control since the power level dictates what links are available for routing. All these interdependences need to be resolved in a manner compatible with the layered and modular architecture for networking systems.. |
