M. Kaleem GALAMALI, Assoc. Prof Nawaz MOHAMUDALLY Abstract – The fields of location-tracking, ubicomp functionalities and MANET transmission strategies are prone to quite a lot of productive research [1-52]. It remains undeniable that the merging of these fields has a long way before fruitfully materialising. An essential factor determining the success of such merging is correct protocol design approaches, which is currently agreed as heuristic in nature and hence unsuitable for implementation [90]. Refinement in middleware and rework in network architecture is also needed [91, 92]. A sharpened objective in this direction of technological progress is achievement of “realism” in design and evaluation of wireless routing protocols [93]. Such studies may yield more suitable components for studies in predictability in ubicomp. “Realism” is a tardy process since it drags along each and every feature related to ubicomp. One such feature was explored in a prior paper [21] to assess the trend of Overall Fairness Ratio (OFR) readable for CBRs under different sets of node densities in ubicomp environments. This study was corroborated by the related study of trends for each OFR parameter of equations [37]. To embrace “realism” in knowledge of these trends, in this paper, the next investigation required is stated as: “What are observable critical values in OFR trends over varying node densities and trends of such critical values?” Such knowledge will eventually lead to the design of more realistic ubicomp scenarios which are better suited for more sustained testing of freshly designed middleware components and communication protocols. The work presented here is a follow-up of previous ones[1-52].

Introduction MANETS remain a fulfilling solution to scant resource availability in ubicomp, in which the load of energy requirements is distributed among cooperating nodes in the topography. This load is radically influenced by varying node densities. An anterior study [21] was designed for finding the trends observable for metric OFR for node densities varying between 7 until 56. The model suggested in that paper [21] combined the exponential and linear models of form: F(x) = a * exp (b*x) + (c*x) + d Following this study, a successive study [37] was conducted to model mathematically the trends of the four parameters observed above. Results obtained are expected to serve towards better understanding of the evolution and predictability of ubicomp environments. With such gently occurring progresses, designers will produce more authentic simulation scenarios over which testing exercises can be conducted for newly built middleware and communication components. The quest now required for metric OFR is the identification of observable critical values obtained during experimentations and formulation of corresponding theoretical trend of such critical values over varying node densities. Five such critical values were observed. The key contribution of this paper is the setting up of the trends of variations for each of the five critical values observed for metric OFR expounded previously [21, 37] englobing node numbers 7 until 56. Such information should compulsorily be presented in an orderly fashion to more fluidly assist ubicomp designers to understand the evolution and predictability of ubicomp behaviour and be better equipped to carry credulous simulation scenarios over which new communication protocol features could be tested.
